PART I

ITEM 1. BUSINESS Overview We are a leading enabler of wireless voice and data services for telecommunications companies worldwide. For over 20 years, we have served as one of the wireless industry’s only operator-neutral intermediaries, solving the challenges that arise as new technologies, standards and protocols emerge. Our data clearinghouse, network and technology services solve technical and operational challenges for the wireless industry by translating incompatible communication standards and protocols and simplifying operator interconnectivity. Our suite of transaction-based services allows operators to deliver seamless voice, data and next generation services to wireless subscribers, including wireless voice and data roaming, Short Message Service (SMS), Multimedia Messaging Services (MMS), Mobile Instant Messaging (MIM), number portability and wireless value-added services.

Demand for our services is driven primarily by wireless voice and data traffic, subscriber roaming activity, SMS and MMS messaging, number porting and next generation IP applications. The global wireless telecommunications industry is expected to grow due to continued subscriber growth, increased usage and deployment of new services. In addition, subscriber adoption of new wireless technologies and services can also drive demand for our services due to the resulting increase in interoperability complexities. The global wireless industry relies on an extensive and complex set of communication standards, technical protocols, network interfaces and systems that must successfully communicate with one another in order to provide voice and data services to subscribers in their local markets and when roaming. The proliferation of these standards has resulted in technological incompatibilities, which are increasingly difficult to manage as new wireless technologies and services are introduced and deployed. We believe that as wireless usage expands and complexity continues to increase, the demand for our services will grow.

We have developed a broad set of innovative interoperability solutions in response to the evolving needs of our customers. Through our integrated suite of services, we enable operators to provide their customers with enhanced wireless services including:

• national and international wireless voice and data roaming;

• wireless data services, including SMS and MMS, across incompatible standards and protocols;

• intelligent network services such as wireless number portability and advanced IP service offerings; and

• prepaid applications and value-added roaming services.

Our service platforms also enable operators to rapidly and cost-effectively deploy next-generation wireless services including enhanced wireless data and wireless value-added services.

We provide our services to more than 650 operators in over 140 countries. We serve most of the largest global wireless operators including AT&T, Sprint Nextel, T-Mobile, Verizon Wireless, America Moviles, Telecom, KDDI, TeliaSonera, Vodafone, VimpelCom and SK Telecom. We believe that maintaining strong relationships with our customers is one of our core competencies and that maintaining these relationships is critical to our success.

We generate the majority of our revenue on a per-transaction basis, and often receive revenue from multiple transactions during a single call or data session. The remainder of our revenue is generated from custom software development fees, hardware sales, professional services, and recurring, non- transaction fees for network connections and software maintenance.

General Developments Financial Highlights For the year ended December 31, 2008, total revenue increased $128.8 million, or 34.1%, to $506.4 million from $377.5 million for the year ended December 31, 2007. The increase in revenues was primarily due to organic volume growth in our Technology Interoperability services and our acquisition of BSG Wireless in December 2007. Net income increased $26.0 million, or 49.7%, to $78.5 million for the year ended December 31, 2008 from $52.4 million for the year ended December 31, 2007. Diluted earnings per share increased $0.37 to $1.15 for the year ended December 31, 2008 from $0.78 for the year ended December 31, 2007.

Technology Interoperability services revenues increased $133.2 million, or 72.2%, to $317.7 million for the year ended December 31, 2008 compared to $184.5 million for the year ended December 31, 2007. The increase in revenues includes $54.9 million of revenues attributable to BSG Wireless, which was included in our income statement beginning on January 1, 2008. Excluding revenues from BSG Wireless, Technology Interoperability revenue grew 42.5%, driven by increases in data clearinghouse services, SMS and MMS interoperability, Mobile Data Roaming (MDR) services and UniRoam®. Number Portability Services revenues increased $2.2 million, or 8.0%, to $29.3 million for the year ended December 31, 2008 from $27.1 million for the year ended December 31, 2007. Revenues from Network services, Call Processing services, Enterprise Solutions and Off-Network Data Base Queries decreased a total of $6.5 million for the year ended December 31, 2008 as compared to 2007.

During 2008, there were several developments that we expect will impact our growth rates in 2009, refer to Business Developments below. Accordingly, we expect our 2009 revenue, excluding Off-Network Database Queries, to be between $460 and $480 million. We expect net income to be between $64.5 and $74 million. We believe the current economic climate will have a mild, but noticeable impact on our roaming business, which is about 60% of our total business. This includes products like our roaming clearinghouse, mobile data roaming, Uniroam, Signaling Solutions and others.

Business Developments Verizon Acquisition of Alltel During the second quarter of 2008, Verizon Wireless (Verizon) announced that it would acquire Alltel Corporation (Alltel). Verizon completed its acquisition of Alltel in January 2009. The impact of the combination of these two customers on us ranges across a variety of services, which affect revenues we receive not only from Verizon and Alltel, but from other roaming partners as well. The revenue impact expected is dependent on Verizon’s integration schedule. Our revenue and net income expectations for 2009 include very specific integration assumptions. These assumptions concern roaming traffic between Verizon and Alltel and other roaming traffic where Verizon has coverage but where Alltel currently uses a different roaming partner. The assumptions highlighted above are based on the current and best information available to us and we can provide no assurance that the actual impact of this transaction will not be more or less than what is reflected in our 2009 revenue and net income expectations.

Alltel/Sprint Insourcing Initiative In order to manage the expense associated with the significant volume growth in mobile data, Alltel and Sprint have directly connected their IP backbone networks. Thus, they no longer use Syniverse as a third party intermediary to manage the connectivity and exchange of billing records between their mobile data roaming platforms beginning in January 2009. Our revenue and net income expectations for 2009 include the impact of this insourcing initiative from the January 2009 effective date.

Number Portability Services We are the leading provider of wireless number portability services to U.S. and Canadian operators, as well as operators in other countries including . These services enable wireless subscribers to switch operators while keeping the same telephone number. As number portability-related technology and operational complexities were identified, we developed solutions that facilitated the exchange of information between operators and transmitted information to regional industry databases. These services route and track the multiple

10 Table of Contents transactions involved in porting numbers between service providers and identify and facilitate problem resolution when porting transactions are not successful. These services also manage the unique challenges of porting numbers between wireless and fixed line operators and from operators who have chosen to manually process porting transactions.

We have been designated as a master database administrator in Singapore, expanding our suite of number portability services. Our centralized number portability database solution for Singapore supplies all mobile operators with the ability to port numbers by providing the ability to agree and coordinate ports between themselves. In the future, we will also support fixed and emerging operators who are required to port numbers in Singapore. In addition, our solution will maintain the master routing database for ported numbers and provide updates to operators for use in routing calls or SMS messages.

We generate revenues from number portability services primarily by charging per-transaction fees and fixed fees. We anticipate that wireless subscriber growth and international implementation of number portability will present opportunities for us to grow our number portability services operations.

Call Processing Services We provide global call handling and fraud management solutions that enable wireless subscribers from one operator to make and receive telephone calls while roaming on another operator’s network. We support global roaming by connecting wireless operators and by resolving geographic and operator differences in subscriber verification, call delivery and signaling network protocols. We also offer wireless operators comprehensive fraud detection and fraud prevention services.

Our primary call processing services include signaling solutions and fraud prevention services. We generate revenues from these services primarily by charging per-transaction processing fees.

Our Call Processing Services include:

• Signaling Solutions. Our services verify a CDMA subscriber’s eligibility to receive service while roaming internationally in another operator’s market. Our signaling solutions also resolve conflicting global numbering plans and overlapping system identifiers to allow subscribers to roam when the visited service provider may not normally recognize the subscriber.

• Fraud Prevention Services. We provide multiple services to operators to minimize the financial losses associated with subscriber fraud. Our fraud profiling solutions collect usage data from mobile switches to create a unique profile for each subscriber based upon the subscriber’s call activity.

Enterprise Solutions We enable wireless operators to offer billing consolidation and data management services to large enterprise customers. Our solutions consolidate customer usage data on to one invoice and offer robust online reporting and analysis tools that enable enterprise customers to manage their telecommunications-related costs. We generate revenues from this service on a per-subscriber processing basis.

Off-Network Database Queries We provide our customers with the ability to connect to various third-party intelligent network database providers. These providers charge us a per- transaction fee for access to their databases, which we pass on to our customers with little or no margin.

Industry Summary The global wireless industry has grown significantly since its inception as wireless services have become increasingly available and affordable. According to CTIA—The Wireless Association, the U.S. wireless industry has grown from an estimated total subscriber base of 97.0 million in 2000 to 262.7 million by mid-year 2008, a 171% increase. CTIA also reported that twelve-month total wireless service revenues grew from $45.3 billion to $143.7 billion in the 8 years ending June 2008, a 217% increase. Additionally, reported annualized wireless minutes has grown at a nearly 50% compound annual growth rate since mid-2000 to over 1.1 trillion in June 2008. This expanding subscriber base and corresponding growth in industry revenues has been driven by improved service quality, greater national and international wireless roaming coverage, decreased pricing and the introduction of new messaging, wireless data and content services.

On a global basis, similar trends have been cited by Informa, an industry research firm. According to an Informa forecast:

• Total worldwide subscribers will rise by 42% from 2006 – 2011 to nearly 3 billion, while global roaming subscribers is expected to rise by 87%

to 566 million over the same period.

• Global roaming revenues are expected to increase by 37% from 2006 – 2011 to nearly $53 billion, with a rising share of total revenues from

roaming.

12 Table of Contents

• Data’s share of mobile roaming revenues is expected to rise steadily from 2006 – 2011 to reach 18%.

Wireless industry growth has been accompanied by a steady introduction of new and often incompatible wireless technologies. This has resulted in the proliferation of different network architectures, including various mobile switch types (such as those manufactured by Alcatel-Lucent, Nortel, Ericsson and Motorola), diverse signaling standards (such as Code Division Multiple Access, or CDMA; Time Division Multiple Access, or TDMA; Global System for Mobile Communication, or GSM; Integrated Digital Enhanced Network, or iDEN; Long Term Evolution, or LTE, WiMAX and Wi-Fi), distinct billing record formats (such as Cellular Intercarrier Billing Exchange Record, or CIBER; Transferred Account Procedure, or TAP; and Remote Authentication Dial-In User Service, or RADIUS) and multiple network protocols (such as Frame Relay, SS7 and Internet Protocol). This has created significant technological incompatibilities and operational challenges for wireless operators.

As a result, many wireless operators utilize third-party technology services providers like us to:

• serve as a trusted intermediary for proprietary data exchange between competitive wireless operators;

• provide centralized, single point connectivity to the systems and networks of multiple operators;

• enable communication between new and legacy operator systems by resolving incompatibilities associated with geographic and operator

variations in communication protocols;

• simplify the operational challenges associated with operator differences in the timing of new technology deployment;

• offer access to a range of intelligent network database services required for enhanced wireless services; and

• rapidly develop new solutions to meet emerging wireless industry technology complexities and to support next generation services such as

wireless data, MIM and VoIP.

Market Opportunity We expect the technology complexities and operational challenges faced by wireless operators to continue to grow as the wireless industry evolves. These complexities and challenges are driven by a variety of wireless industry trends including the growth in the number of wireless telephone subscribers, the volume of wireless roaming telephone calls and the growing volume of SMS and MMS messages and wireless data events. In addition, the emergence of next-generation wireless communication services such as WiMAX, LTE and VoIP, future government mandated changes, and new applications for existing communications services will drive future industry growth.

Technology Interoperability Services The proliferation and evolution of incompatible wireless communication protocols, messaging/data formats and billing standards has made it increasingly difficult for operators to connect systems and networks and to share the information required to offer seamless global wireless voice and data services to subscribers. Technology service providers solve these interoperability problems by offering wireless roaming clearinghouse services, SMS and MMS messaging translation and routing services, and wireless data roaming facilitation and clearinghouse solutions to support emerging mobile data services.

Clearinghouses translate various network signaling and billing protocols to allow different wireless operators to offer and be compensated for roaming services. These wireless clearinghouses serve as trusted third parties for the collection, translation and distribution of the information required to monitor and invoice services provided by one operator to numerous other operators’ customers. Demand for clearinghouse services is primarily driven by the number of domestic and international wireless roaming subscribers. We expect that increased roaming traffic volumes will drive incremental technology interoperability and clearinghouse transaction volumes for the industry.

The growth of SMS and MMS messaging is also driving significant operational challenges for wireless operators. Cross-operator SMS messaging and MMS messaging requires extensive network connectivity and complex message protocol conversion between wireless operators. Operator-grade message translation and routing are critical to wireless operators who increasingly rely on messaging services to drive incremental revenue growth and to improve customer retention.

According to Portio Research, worldwide SMS traffic is expected to grow from 2.6 trillion in 2007 to 5.5 trillion in 2013 (a compound annual growth rate of around 13 percent), with this growth expected to be driven by a surge in the SMS traffic in Asia Pacific. Worldwide MMS traffic is expected to grow from 51.4 billion in 2007 to 171.7 billion in 2013 (a compound annual growth rate of around 22 percent), and this growth is expected to be driven by the surge in MMS traffic in the Asia Pacific and European regions.

In September 2008, we announced we are working with Colibria to develop an Advanced Messaging Hub solution. This solution, named Syniverse NEXT, provides interworking between operators for the exchange of presence data, instant messaging (IM), SMS, and MMS messages across networks, protocols and message types. Operators will be able to offer their subscribers more interactive, intuitive and convenient presence-based messaging services, and give those subscribers the ability to spontaneously communicate and share experiences with individuals, groups and social networking communities. We have structured our agreement with Colibria as a joint development agreement where we each bring our core capabilities to develop a solution where we will own the intellectual property.

The emergence of mobile data and premium content services are also driving operator demand for clearinghouse services, translation services and roaming facilitation services. This growth has been and will continue to be supported by the deployment of next generation wireless data networks. We believe the increase in wireless data roaming will drive the need for wireless data clearinghouse services that simplify network connectivity and the exchange of invoicing data between multiple operators.

Network Services SS7 networks are a core element of today’s telecommunications infrastructure. SS7 is the telecommunications industry’s standard network signaling protocol used by substantially all operators to enable the setup and delivery of telephone calls and to offer enhanced calling features like caller ID. Outsourced network services provide operators cost effective, single point connectivity to an SS7 network, other widely used communication networks and critical databases. As a result, operators avoid the cost and complexity of managing individual network connections to multiple operators, eliminate the expense of licensing and maintaining intelligent network revenues databases and reduce the need for building capital-intensive network infrastructure. Drivers of network services include wireless subscriber growth, wireless roaming call volume growth, wireless roaming data growth and SMS messaging volume growth.

In addition, wireless data roaming requires operators to support packet-switched, Internet Protocol-based communications protocols including General Packet Radio Service, or GPRS; High Speed Packet Access, or HSPA; 1 x Radio Transmission Technology, or 1xRTT; and 1 x Evolution—Data Optimized, or 1xEV-DO (technology designed to double voice capacity and support faster data transmission). Technology service providers support wireless data roaming services and enable subscribers to access their home wireless data services (such as public Internet, corporate intranets, e-mail and m-commerce) while abroad or beyond the reach of their home network. The emergence of Internet Protocol-based signaling solutions and database services associated with VoIP will also require network, routing and translation services to communicate with legacy networks. VoIP offers traditional voice telephone services but at a significantly lower cost by bypassing the traditional telephone network.

In February 2009, we launched our IP Packet eXchange Network Transport solution, or IPX, to help global operators keep up with increasing volumes while maintaining quality of service for subscribers. IPX provides

14 Table of Contents operators access to a full suite of mobile data services via a single ubiquitous network while supporting emerging 3G Plus solutions. Via this global network solution, operators connect to a single network to utilize a full suite of wireless data services. This approach means operators can reduce costs by adding additional services or increasing capacity without needing to connect to additional networks.

Number Portability Services In 1996, the United States Federal Communications Commission, or FCC, mandated number portability services to encourage competition by permitting wireless subscribers to change operators while retaining their current telephone numbers. In 2005, Canadian regulators also mandated wireless number portability. Other jurisdictions around the world are currently mandating or are analyzing the need for the implementation of number portability services. To facilitate the portability of wireless telephone numbers, operators exchange information with other operators and transmit information to regional number portability databases in order to support call routing. Implementation of number portability services impacts nearly every system within operator operations including network signaling and routing, switching, billing, point of sale and customer care.

Technology service providers enable wireless operators to implement number portability services to their customers by streamlining the ordering and communication processes that organize, prioritize and route number portability transactions between wireless operators and industry databases. These services must be able to route and track the multiple transactions involved in porting numbers between service providers, identify and facilitate problem resolution, manage the unique challenges of porting between fixed line and wireless operators, and interface to operators who have chosen less automated porting solutions.

Following the introduction of number portability services in the U.S., the wireless industry experienced rapid consumer adoption. We expect the drivers of number portability services demand will be continued increase in the number of wireless subscribers, operator competition and increased regulatory focus, and adoption of number portability services in other countries around the world.

Call Processing Services Call processing solutions support the proper authentication, handling and routing of telephone calls in order to reduce fraud and to allow CDMA wireless subscribers to make and accept telephone calls while roaming on another operator’s network. Wireless roaming growth is causing new call routing and delivery complexities for operators. Due to geographic and operator differences in subscriber verification, call delivery and signaling network protocols, these services require extensive data management capabilities.

Drivers of call processing demand include international wireless subscriber growth and international wireless roaming call volume growth. Operators are increasingly using SS7 networks to replace traditional call processing functionality and to address wireless subscriber fraud issues.

Competition We have a number of competitors for each specific service that we offer.

we intend to pursue sales opportunities with non-traditional customer segments and new entrants into the mobile messaging market, such as cable companies, Internet providers and portals. We intend to continue to sell incremental services to our existing customers to further diversify our revenue and increase per-customer revenues.

• Continue to expand globally. We are aggressively pursuing global expansion opportunities in new markets. We have continued to expand our sales and support offices in Europe, Asia Pacific and Latin America. This expansion has helped us win contracts with leading operators in many countries including the United Kingdom, France, China, Italy, Russia and India. For the year ended December 31, 2008, 27.9% of our total

revenues (excluding off-network database queries) were generated outside of North America as compared to 21.7% for the year ended December 31, 2007. We expect the percentage of our revenue generated outside North America to increase due to increasing sales to new and existing global customers. In December 2007, we acquired BSG Wireless. This acquisition allows us to combine our industry-leading technology interoperability and network services capabilities with BSG Wireless’ GSM data clearing expertise, European, Middle Eastern and Asian operator relationships, and financial clearing and settlement capabilities.

ITEM 1A. RISK FACTORS System failures, security breaches, delays and other problems could harm our reputation and business, cause us to lose customers and expose us to customer liability. Our success depends on our ability to provide reliable services to our customers. Our operations could be interrupted by any damage to or failure of:

• our computer software or hardware, or our customers’ or suppliers’ computer software or hardware;

• our networks, our customers’ networks or our suppliers’ networks; and

• our connections and outsourced service arrangements with third parties.

Our systems and operations are also vulnerable to damage or interruption from:

• power loss, transmission cable cuts and other telecommunications failures;

• hurricanes, fires, earthquakes, floods and other natural disasters;

• interruption of service due to potential facility migrations;

• computer viruses or software defects;

• physical or electronic break-ins, sabotage, intentional acts of vandalism and similar events; and

• errors by our employees or third-party service providers.

Because many of our services play a mission-critical role for our customers, any damage to or failure of the infrastructure we rely on, including that of our customers and vendors, could disrupt the operation of our network and the provision of our services, result in the loss of current and potential customers and expose us to potential customer liability.

We depend on a small number of customers for a significant portion of our revenues and the loss of any of our major customers would harm us. Our three largest customers for the year ended December 31, 2008 represented approximately 32.1% of our revenues in the aggregate, while our ten largest customers for the year ended December 31, 2008 represented approximately 55.8% of our revenues in the aggregate. For the year ended December 31, 2008, we generated revenues from services provided to , Verizon Wireless and their affiliates, which collectively is our largest customer, of approximately $76.0 million, or 15.0% of our revenues. No other customer accounted for more than 10% of our revenues for the year ended December 31, 2008. We expect to continue to depend upon a small number of customers for a significant percentage of our revenues. Because our major customers represent such a large part of our business, the loss of any of our major customers would negatively impact our business.

Most of our customer contracts do not provide for minimum payments at or near our historical levels of revenues from these customers. Although some of our customer contracts require our customers to make minimum payments to us, these minimum payments are substantially less than the revenues that we have historically earned from these customers. If our customers decide for any reason not to continue to purchase services from us at current levels or at current prices, to terminate their contracts with us or not to renew their contracts with us, our revenues would decline.

Future consolidation among our customers may cause us to lose transaction volume and reduce our prices, which would negatively impact our financial performance. In the past, consolidation among our customers has caused us to lose transaction volume and to reduce prices. In the future, our transaction volume and pricing may decline for similar reasons. Such consolidation activities may take the form of business combinations, strategic partnerships, or other business arrangements between the operators. For example, during the second quarter of 2008 Verizon Wireless (Verizon) announced that it would acquire Alltel Corporation (Alltel). Verizon completed its acquisition of Alltel in January 2009. The impact to us of the consolidation is described under “Business Developments” in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

20 Table of Contents

We may not be able to expand our customer base to make up any revenue declines if we lose customers or if our transaction volumes decline as a result of consolidation activities. Our attempts to diversify our customer base and reduce our reliance on particular customers may not be successful.

If we do not adapt to rapid technological change in the telecommunications industry, we could lose customers or market share. Our industry is characterized by rapid technological change, frequent new service introductions and changing customer demands. Significant technological changes could make our technology and services obsolete. Our success depends in part on our ability to adapt to our rapidly changing market by continually improving the features, functionality, reliability and responsiveness of our existing services and by successfully developing, introducing and marketing new features, services and applications to meet changing customer needs. We cannot assure you that we will be able to adapt to these challenges or respond successfully or in a cost-effective way to adequately meet them. Our failure to do so would impair our ability to compete, retain customers or maintain our financial performance. We sell our services primarily to telecommunications companies. Our future revenues and profits will depend, in part, on our ability to sell to new market participants.

The market for our services is intensely competitive and many of our competitors have significant advantages over us. We compete in markets that are intensely competitive and rapidly changing. Increased competition could result in fewer customer orders, reduced pricing, reduced gross and operating margins and loss of market share, any of which could harm our business. We face competition from large, well-funded providers of similar services, such as VeriSign, Neustar, Sybase, MACH and other existing communications, billing and technology companies. We are aware of major Internet service providers, software developers and smaller entrepreneurial companies that are focusing significant resources on developing and marketing services that will compete with the services we offer. We anticipate increased competition in the telecommunications industry and the entrance of new competitors into our business.

We expect that competition will remain intense in the near term and that our primary long-term competitors may not yet have entered the market. Many of our current and potential competitors have significantly more employees and greater financial, technical, marketing and other resources than we do. Our competitors may be able to respond more quickly to new or emerging technologies and changes in customer requirements than we can. In addition, many of our current and potential competitors have greater name recognition and more extensive customer bases that they can use to their advantage.

Our continued expansion into international markets is subject to uncertainties that could affect our operating results. Our growth strategy contemplates continued expansion of our operations into foreign jurisdictions. International operations and business expansion plans are subject to numerous risks, including:

• the difficulty of enforcing agreements and collecting receivables through certain foreign legal systems;

• fluctuations in currency exchange rates;

• foreign customers may have longer payment cycles than customers in the U.S.;

• U.S. Department of Commerce export controls;

• tax rates in some foreign countries may exceed those of the U.S. and foreign earnings may be subject to withholdings requirements or the

imposition of tariffs, exchange controls or other restrictions;

• general economic and political conditions in the countries where we operate may have an adverse effect on our operations in those countries or

not be favorable to our growth strategy;

21 Table of Contents

• unexpected changes in regulatory requirements;

• the difficulties associated with managing a large organization spread throughout various countries;

• the risk that foreign governments may adopt regulations or take other actions that would have a direct or indirect adverse impact on our business

and market opportunities; and

• the potential difficulty in enforcing intellectual property rights in certain foreign countries.

For the year ended December 31, 2008, 27.7% of our total revenues (excluding off-network database queries) were generated outside of North America as compared to 21.7% for the year ended December 31, 2007. As we continue to expand our business globally, our success will depend, in large part, on our ability to anticipate and effectively manage these and other risks associated with our international operations. However, any of these factors could result in higher costs or reduced revenues for our international operations.

The costs and difficulties of acquiring and integrating complementary businesses and technologies could impede our future growth, diminish our competitiveness and harm our operations. As part of our growth strategy, we intend to consider acquiring complementary businesses. Future acquisitions could result in potentially dilutive issuances of equity securities, the incurrence of debt and contingent liabilities and an increase in amortization expense related to identifiable intangible assets acquired, which could harm our business, financial condition and results of operations. Risks we could face with respect to acquisitions include:

• greater than expected costs, management time and effort involved in identifying, completing and integrating acquisitions;

• potential disruption of our ongoing business and difficulty in maintaining our standards, controls, information systems and procedures;

• entering into markets and acquiring technologies in areas in which we have little experience;

• acquiring intellectual property which may be subject to various challenges from others;

• the inability to successfully integrate the services, products and personnel of any acquisition into our operations;

• the inability to achieve expected synergies;

• a need to incur debt, which may reduce our cash available for operations and other uses, or a need to issue equity securities, which may dilute the

ownership interests of existing stockholders; and

• realizing little, if any, return on our investment.

Integrating our operations with the BSG Wireless operations may prove to be disruptive and could result in the combined businesses failing to meet our expectations. We expect to integrate the operations of BSG Wireless into our own and achieve certain cost saving synergies. We cannot be sure that we will realize these anticipated benefits in full or at all. Achieving the expected benefits from the acquisition will depend, in part, upon whether the operations and personnel of BSG Wireless can be integrated in an efficient and effective manner with our existing business. Our management team may encounter unforeseen difficulties in managing the integration of the two businesses. Additionally, difficulties in integration may result in adverse developments in our relationships with customers and suppliers. The process of integrating formerly separately operated businesses may prove disruptive to both businesses, may take longer than we anticipate and may cause an interruption of and have a material adverse effect on our combined businesses.

22 Table of Contents

Even if we are able to successfully integrate the business of BSG Wireless into our operations, we may not realize the anticipated cost saving synergies of the BSG Wireless acquisition on the time table currently contemplated, or at all. The BSG Wireless acquisition was based, in part, on the expectation that the acquisition would result in various cost saving synergies. Even if we are able to successfully integrate the business of BSG Wireless into our operations, there can be no assurance that we will realize the expected cost saving synergies on the timetable currently contemplated, or at all. We expect to incur significant restructuring charges (including severance) and transition expenses in connection with these cost saving synergies. Achieving the expected cost saving synergies, as well as the costs of achieving them, is subject to a number of uncertainties and other factors. If these factors limit our ability to achieve the expected cost saving synergies of the acquisition or if the related costs exceed our estimates, our expectations of future results of operations, including the cost saving synergies expected to result from the acquisition, may not be met. Additionally, the actions we take to achieve cost saving synergies could have unintended consequences that adversely affect our business. If we encounter difficulties in achieving the expected cost saving synergies or do not achieve such cost saving synergies, we incur significantly greater costs related to such cost saving synergies than we anticipate or our activities related to such cost saving synergies have unintended consequences, our business, financial condition and results of operations could be adversely affected.

Difficulty in integrating technology may harm our business. Following the acquisition of BSG Wireless, we have begun to integrate certain technology platforms. This process may be slower or more difficult than we currently contemplate. Furthermore, we may encounter unanticipated difficulties in this process, which could cause integration difficulties and customer disruptions. The measures that we have taken to date or plan to take in the future may not adequately resolve those issues. If we fail to successfully integrate technology platforms, our ability to achieve cost efficiencies expected to result from the acquisition of BSG Wireless may be impaired, which may adversely affect our future financial position, results of operations and customer relationships.

Our failure to achieve or sustain market acceptance at desired pricing levels or transaction volumes could impact our ability to maintain profitability or positive cash flow. Competition and industry consolidation have resulted in pricing pressure, which we expect to continue in the future and which we expect to continue to address through our volume-based pricing strategy. This pricing pressure could cause large reductions in the selling price of our services. For example, consolidation in the wireless services industry in the United States over the past several years could give our customers increased transaction volume leverage in pricing negotiations. Our competitors or our customers’ in-house solutions may also provide services at a lower cost, significantly increasing pricing pressures on us. While historically pricing pressure has been largely offset by volume increases and the introduction of new services, in the future we may not be able to offset the effects of any price reductions.

The inability of our customers to successfully implement our services could harm our business. Significant technical challenges can arise for our customers when they implement our services. Our customers’ ability to support the deployment of our services and integrate them successfully within their operations depends, in part, on our customers’ technological capabilities and the level of technological complexity involved. Difficulty in deploying those services could increase our customer service support costs, delay the recognition of revenues until the services are implemented and reduce our operating margins.

Our reliance on third-party providers for communications software, hardware and infrastructure exposes us to a variety of risks we cannot control. Our success depends on software, equipment, network connectivity and infrastructure hosting services supplied by our vendors and customers. We cannot assure you that we will be able to continue to purchase the

23 Table of Contents necessary software, equipment and services from these vendors on acceptable terms or at all. If we are unable to maintain current purchasing terms or ensure service availability with these vendors and customers, we may lose customers and experience an increase in costs in seeking alternative supplier services.

Our business also depends upon the capacity, reliability and security of the infrastructure owned and managed by third parties, including our vendors and customers, that is used by our technology interoperability services, network services, number portability services, call processing services and enterprise solutions. We have no control over the operation, quality or maintenance of a significant portion of that infrastructure and whether those third parties will upgrade or improve their software, equipment and services to meet our and our customers’ evolving requirements. We depend on these companies to maintain the operational integrity of our services. If one or more of these companies is unable or unwilling to supply or expand its levels of service to us in the future, our operations could be severely interrupted. In addition, rapid changes in the telecommunications industry have led to industry consolidation. This consolidation may cause the availability, pricing and quality of the services we use to vary and could lengthen the amount of time it takes to deliver the services that we use.

Capacity limits on our network and application platforms may be difficult to project and we may not be able to expand and upgrade our systems to meet increased use. As customers’ usage of our services increases, we will need to expand and upgrade our network and application platforms. We may not be able to accurately project the rate of increase in usage of our services. In addition, we may not be able to expand and upgrade, in a timely manner, our systems, networks and application platforms to accommodate increased usage of our services. If we do not appropriately expand and upgrade our systems and networks and application platforms, we may lose customers and our operating performance may suffer.

Financial and operating difficulties in the telecommunications sector may negatively affect our customers and our company. Historically, the telecommunications sector has experienced significant challenges resulting in excess capacity, poor operating results and financing difficulties. Because we operate in the telecommunications sector, we may also be negatively impacted. While the sector has recently improved, some of our customers continue to have uncertain financial conditions. The impact of these conditions on us could include slower collections on accounts receivable, higher bad debt expense, uncertainties due to possible customer bankruptcies, lower pricing on new customer contracts, lower revenues due to lower usage by the end customer and possible consolidation among our customers, which will put our customers and operating performance at risk.

We may need additional capital in the future and it may not be available on acceptable terms, or at all. We may require more capital in the future to:

• fund our operations;

• enhance and expand the range of services we offer;

• maintain and expand our network; and

• respond to competitive pressures and potential strategic opportunities, such as investments, acquisitions and international expansion. We cannot assure you that additional financing will be available on terms favorable to us, or at all. The terms of available financing may place limits on our financial and operating flexibility. In addition, our senior credit facility and the indenture governing our 7 3/4% senior subordinated notes contain financial and other restrictive covenants that will limit our ability to incur indebtedness or obtain financing. If adequate funds are not available on acceptable terms, we may be forced to reduce our operations or abandon expansion opportunities.

24 Table of Contents

Moreover, even if we are able to continue our operations, our failure to obtain additional financing could reduce our competitiveness as our competitors may provide better-maintained networks or offer an expanded range of services.

Our substantial indebtedness could have a material adverse effect on our financial health and prevent us from fulfilling our obligations. We have significant debt service obligations. As of December 31, 2008, we had outstanding indebtedness of approximately $513.8 million (including the current portion of $3.4 million). We are the borrower of all of this outstanding indebtedness.

Our substantial debt could have important consequences to investors. For example, it could:

• make it more difficult for us to satisfy our obligations with respect to our indebtedness;

• require us to dedicate a substantial portion of our cash flow from operations to payments on our debt, which will reduce the funds available for

working capital, capital and development expenditures, acquisitions and other general corporate purposes;

• limit our flexibility in planning for, or reacting to, changes in the manufacture, production, distribution or marketing of our services, customer

demand, competitive pressures and the industries we serve;

• place us at a competitive disadvantage compared to our competitors that are less leveraged than we are;

• increase our vulnerability to both general and industry-specific adverse economic conditions; and

• limit our ability to borrow additional funds.

We may incur substantial additional debt in the future. The addition of further debt to our current debt levels could intensify the leverage-related risks that we now face.

In addition, our debt contains financial and other restrictive covenants that may limit our ability to engage in activities that may be in our long-term best interests. Our failure to comply with those covenants could result in an event of default, which if not cured or waived, could result in the acceleration of all our debts.

Our stock price may be volatile. The trading price of our common stock could be subject to wide fluctuations in response to various factors, some of which are beyond our control, such as:

• actual or anticipated variations in quarterly results of operations;

• changes in intellectual property rights of us or our competitors;

• announcements of technological innovations;

• the introduction of new products or changes in product;

• pricing by us or our competitors;

• changes in financial estimates by securities analysts;

• announcements of significant acquisitions, strategic partnerships, joint ventures or capital commitments by us or our competitors;

• additions or departures of key personnel; and

• generally adverse market conditions.

25 Table of Contents

We have anti-takeover protections that may delay or prevent a change in control that could benefit our stockholders. We have adopted a stockholder rights plan that may discourage, delay or prevent a change of control and make any future unsolicited acquisition attempt more difficult.

On November 16, 2008, our Board of Directors adopted a stockholder rights plan which declared a dividend of one preferred share purchase right (the “Right”) for each outstanding share of Common Stock, par value $0.001 per share (the “Common Shares”), of the Company. The dividend was payable on November 28, 2008 to the stockholders of record on that date. Each Right entitles the registered holder to purchase from the Company one one-thousandth of a share (a “Unit”) of Series A Junior Participating Preferred Stock, par value $0.01 per share (the “Preferred Shares”), at a price of $33 per one one-thousandth of a Preferred Share (the “Purchase Price”), subject to adjustment. Each Unit has designations and powers, preferences and rights, and the qualifications, limitations and restrictions designed to make it the economic equivalent of a Common Share. The description and terms of the Rights are set forth in the Rights Agreement dated November 16, 2008.

Under the plan, the stock rights will become exercisable only when a public announcement or notice to Syniverse has been made that a person or group has acquired, or obtained the right to acquire beneficial ownership of 15% or more of the outstanding shares of Syniverse’s Common Shares, other than as a result of an offer approved by the Board of Directors of the Company and (ii) 10 business days (or, if determined by the Board of Directors, a specified or unspecified later date) following the commencement or announcement of an intention to make a tender offer or exchange offer which, if successful, would cause the bidder to own 15% of more of the outstanding Common Shares. Until a Right is exercised, the holder thereof, as such, will have no rights as a stockholder of Syniverse, other than rights resulting from such holder’s ownership of Common Shares, including, without limitation, the right to vote or to receive dividends.

Regulations affecting our customers and us and future regulations to which they or we may become subject may harm our business. Although we do not offer voice-grade or data services that are deemed to be common carrier telecommunication services, certain of the services we offer are subject to regulation by the United States Federal Communications Commission, or FCC, that could have an indirect effect on our business. The U.S. telecommunications industry has been subject to continuing deregulation since 1984 and the European and Asian telecommunications industries are also subject to continued deregulation. We cannot predict when, or upon what terms and conditions, further regulation or deregulation might occur or the effect regulation or deregulation may have on our business. Several services that we offer may be indirectly affected by regulations imposed upon potential users of those services, which may increase our costs of operations. In addition, future services we may provide could be subject to direct regulation.

We may not be able to receive or retain licenses or authorizations that may be required for us to sell our services internationally. The sales and marketing of our services internationally are subject to the U.S. Export Control regime. Services of a commercial nature are subject to regulatory control by the Department of Commerce’s Bureau of Export Administration and to Export Administration regulations. In the future, Congress may require us to obtain export licenses or other export authorizations to export our services abroad, depending upon the nature of services being exported, as well as the country to which the export is to be made. We cannot assure you that any of our applications for export licenses or other authorizations will be granted or approved. Furthermore, the export license/export authorization process is often time-consuming. Violation of export control regulations could subject us to fines and other penalties, such as losing the ability to export for a period of years, which would limit our revenue growth opportunities and significantly hinder our attempts to expand our business internationally.

Failure to protect our intellectual property rights adequately may have a material adverse affect on our results of operations or our ability to compete. We attempt to protect our intellectual property rights in the United States and in foreign countries through a combination of patent, trademark, copyright and trade secret laws, as well as licensing agreements and agreements preventing the unauthorized disclosure and use of our intellectual property. We cannot assure you that these protections will be adequate to prevent competitors from copying or reverse engineering our services, or independently developing and marketing services that are substantially equivalent to or superior to our own. Moreover, third parties may be able to successfully challenge, oppose, invalidate or circumvent our patents, trademarks, copyrights and trade secret rights. We may fail or be unable to obtain or maintain adequate protections for certain of our intellectual property in the United States or certain foreign countries or our intellectual property rights may not receive the same degree of protection in foreign countries as they would in the United States because of the differences in foreign trademark, patent and other laws concerning proprietary rights. Such failure or inability to obtain or maintain adequate protection of our intellectual property rights for any reason could have a material adverse effect on our business, results of operations and financial condition.

Monitoring and protecting our intellectual property rights is difficult and costly. From time to time, we may be required to initiate litigation or other action to enforce our intellectual property rights or to establish their validity. Such action could result in substantial cost and diversion of resources and management attention and we cannot assure you that any such action will be successful.

If third parties claim that we are in violation of their intellectual property rights, it could have a negative impact on our results of operations and ability to compete. We face the risk of claims that we have infringed the intellectual property rights of third parties. For example, significant litigation regarding patent rights exists in our industry. Our competitors in both the U.S. and foreign countries, many of which have substantially greater resources than we have and have made substantial investments in competing technologies, may have applied for or obtained, or may in the future apply for and obtain, patents that will prevent, limit or otherwise interfere with our ability to make and sell our products and services. We have not conducted an independent review of patents issued to third parties. The large number of patents, the rapid rate of new patent issuances, the complexities of the technology involved and uncertainty of litigation increase the risk of business assets and management’s attention being diverted to patent litigation.

It is possible that third parties will make claims of infringement against us or against our licenses in connection with their use of our technology. Any claims, even those without merit, could:

• be expensive and time-consuming to defend;

• cause us to cease making, licensing, using or selling equipment, services or products that incorporate the challenged intellectual property;

• require us to redesign our equipment, services or products, if feasible;

• divert management’s attention and resources; and

• require us to enter into royalty or licensing agreements in order to obtain the right to use necessary intellectual property.

Any royalty or licensing agreements, if required, may not be available to us on acceptable terms or at all. A successful claim of infringement against us or one of our licensees in connection with a third party’s use of our technology could result in our being required to pay significant damages, enter into costly license or royalty agreements or stop the sale of certain products, any of which could have a negative impact on our operating profits and harm our future prospects.

27 Table of Contents

If our products infringe on the intellectual property rights of others, we may be required to indemnify our customers for any damages they suffer. We generally indemnify our customers with respect to infringement by our products of the proprietary rights of third parties. Third parties may assert infringement claims against our customers. These claims may require us to initiate or defend protracted and costly litigation on behalf of our customers, regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of our customers or may be required to obtain licenses for the products they use. If we cannot obtain all necessary licenses on commercially reasonable terms, our customers may be forced to stop using our products.

We depend on key personnel to manage our business effectively and may not be successful in attracting and retaining such personnel. We depend on the performance of our senior management team and other key employees. Our success also depends on our ability to attract, integrate, train, retain and motivate these individuals and additional highly skilled technical and sales and marketing personnel, both in the United States and abroad. The loss of the services of any of our senior management team or other key employees or failure to attract, integrate, train, retain and motivate additional key employees could harm our business.

Our customers may develop in-house solutions and migrate part or all of the services that we provide them to these in-house solutions. We believe that certain customers may choose to internally deploy certain functionality currently provided by our services. In recent years, we have experienced a loss of revenue streams from certain of our services as some of our customers have decided to meet their needs for these services in-house. For example, in order to manage the expense associated with the significant volume growth in mobile data, Alltel and Sprint have directly connected their IP backbone networks. Thus, they no longer use Syniverse as a third party intermediary to manage the connectivity and exchange of billing records between their mobile data roaming platforms beginning in January 2009.

Fluctuations in currency exchange rates may adversely affect our results of operations. A growing part of our business consists of sales made to customers outside the United States. A portion of the net revenues we receive from such sales is denominated in currencies other than the U.S. dollar. Additionally, portions of our cost of net revenues and our other operating expenses are incurred by our international operations and denominated in local currencies. While fluctuations in the value of these net revenues, costs and expenses as measured in U.S. dollars have not materially affected our results of operations historically, we cannot assure you that adverse currency exchange rate fluctuations will not have a material impact in the future. In addition, our balance sheet reflects non-U.S. dollar denominated assets and liabilities, including intercompany balances eliminated in consolidation, which can be adversely affected by fluctuations in currency exchange rates.

The current national and world-wide financial crisis could adversely affect our operating results and stock price in a material manner. General world-wide economic conditions have recently deteriorated due to credit conditions resulting from the recent financial crisis affecting the banking system and financial markets, slower economic activity, concerns about inflation and deflation, volatility in energy costs, decreased consumer confidence, reduced corporate profits and capital spending, adverse business conditions and liquidity concerns in the wireless communications markets. These conditions make it difficult for our customers, our vendors and us to accurately forecast and plan future business activities, and they could cause U.S. and foreign businesses to further slow spending on our services. Furthermore, during challenging economic times such as the current downturn, our customers may face issues gaining timely access to sufficient credit, which could impair their ability to make timely payments to us. If that were to occur, we may be required to increase our allowance for doubtful accounts and our accounts

28 Table of Contents receivable outstanding would be negatively impacted. The current economic downturn and any future downturn may reduce our revenue or our percentage of revenue growth on a quarter-to-quarter basis. We cannot predict the timing, strength or duration of any economic slowdown or subsequent economic recovery, world-wide, or in the telecommunications industry or the wireless communications markets. If the economy or the markets in which we operate do not improve from their current condition or if they continue to deteriorate, our customers or potential customers could continue to reduce or further delay their use of our services, which would adversely impact our revenues and ultimately our profitability. In addition, we may record additional charges related to the restructuring of our business and the impairment of our goodwill and other long-lived assets, and our business, financial condition and results of operations will likely be materially and adversely affected.

Our revenues from roaming clearinghouse are dependant upon subscribers continuing to travel. Worsening economic conditions may impact the frequency with which subscribers travel and consequently decrease our revenues. Demand for our services is driven primarily by wireless voice and data traffic, subscriber roaming activity, SMS and MMS messaging, number porting and next generation IP applications. The global wireless telecommunications industry is expected to grow due to continued subscriber growth, increased usage and deployment of new services. However, changes in subscriber usage patterns could be affected in any recession or economic downturn in the United States or any other country where we do business and could negatively impact the number of transactions processed and adversely affect our revenues and earnings.

If the national and world-wide financial crisis intensifies, potential disruptions in the capital and credit markets may adversely affect our business, including the availability and cost of short-term funds for liquidity requirements and banks’ ability to meet long-term commitments; each of which could adversely affect our results of operations, cash flows and financial condition. Disruptions in the capital and credit markets, as have been experienced during 2008, could adversely affect our ability to draw on our revolving credit facilities. Our access to funds under our revolving credit facilities is dependent on the ability of the banks that are parties to the facilities to meet their funding commitments. Those banks may not be able to meet their funding commitments to us if they experience shortages of capital and liquidity or if they experience excessive volumes of borrowing requests from us and other borrowers within a short period of time. For example, in 2008, Lehman Commercial Paper Inc. (Lehman CPI) filed a petition under Chapter 11 of the U.S. Bankruptcy Code with the U.S. Bankruptcy Court for the Southern District of New York. Lehman CPI is the administrative agent of our senior credit facility. Lehman CPI has $28.2 million (45.5 percent) of the $62 million in commitments under our undrawn revolving credit line. It is doubtful Lehman CPI will honor its obligations under the revolving credit line.

Longer term disruptions in the capital and credit markets as a result of uncertainty, changing or increased regulation, reduced alternatives or failures of significant financial institutions could adversely affect our access to liquidity needed for our business. Any disruption could require us to take measures to conserve cash until the markets stabilize or until alternative credit arrangements or other funding for our business needs can be arranged. Such measures could include deferring capital expenditures, acquisition activities or other discretionary uses of cash.

Our financial results may be adversely affected if we have to impair our intangible assets or goodwill. As a result of our acquisitions, a significant portion of our total assets consist of intangible assets (including goodwill). Goodwill and intangible assets, net of amortization, together accounted for approximately 67% and 77% of the total assets on our balance sheet as of December 31, 2008 and December 31, 2007, respectively. We may not realize the full fair value of our intangible assets and goodwill. We expect to engage in additional acquisitions, which may result in our recognition of additional intangible assets and goodwill. Under current accounting standards, we are able to amortize certain intangible assets over the useful life of the asset, while goodwill is not amortized. We evaluate on a regular basis whether all or a portion of our goodwill intangible assets may be impaired. Under current accounting rules, any determination that impairment has occurred would

29 Table of Contents require us to write-off the impaired portion of goodwill and such intangible assets, resulting in a charge to our earnings. Such a write-off could adversely affect our financial condition and results of operations.

ITEM 1B. UNRESOLVED STAFF COMMENTS None.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following discussion and analysis contains forward-looking statements about our plans and expectations of what may happen in the future.

Business We are a leading enabler of wireless voice and data services for telecommunications companies worldwide. For over 20 years, we have served as one of the wireless industry’s only operator-neutral intermediaries, solving the challenges that arise as new technologies, standards and protocols emerge. Our data clearinghouse, network and technology services solve technical and operational challenges for the wireless industry by translating incompatible communication standards and protocols and simplifying operator interconnectivity. Our suite of transaction-based services allows operators to deliver seamless voice, data and next generation services to wireless subscribers, including wireless voice and data roaming, SMS, MMS and MIM, number portability and wireless value-added services.

Demand for our services is driven primarily by wireless voice and data traffic, subscriber roaming activity, SMS and MMS messaging, number porting and next generation IP applications. The global wireless telecommunications industry is expected to grow due to continued subscriber growth, increased usage and deployment of new services. In addition, subscriber adoption of new wireless technologies and services can also drive demand for our services due to the resulting increase in interoperability complexities. The global wireless industry relies on an extensive and complex set of communication standards, technical protocols, network interfaces and systems that must successfully communicate with one another in order to provide voice and data services to subscribers in their local markets and when roaming. The proliferation of these standards has resulted in technological incompatibilities, which are increasingly difficult to manage as new wireless technologies and services are introduced and deployed. We believe that as wireless usage expands and complexity continues to increase, the demand for our services will grow.

We have developed a broad set of innovative interoperability solutions in response to the evolving needs of our customers. Through our integrated suite of services, we enable operators to provide their customers with enhanced wireless services including:

• national and international wireless voice and data roaming;

• wireless data services, including SMS, MMS and MIM, across incompatible standards and protocols;

• intelligent network services such as wireless number portability and advanced IP service offerings; and

• prepaid applications and value-added roaming services.

Our service platforms also enable operators to rapidly and cost-effectively deploy next-generation wireless services including enhanced wireless data, wireless Voice-over-Internet Protocol, or VoIP, and wireless value-added services.

We provide our services to more than 650 operators in over 140 countries. We serve most of the largest global wireless operators including AT&T, Sprint/Nextel, T-Mobile, Verizon Wireless, America Moviles, China Telecom, KDDI, TeliaSonera, Vodafone, VimpelCom and SK Telecom. We believe that maintaining strong relationships with our customers is one of our core competencies and that maintaining these relationships is critical to our success.

Services We provide an integrated suite of services to wireless telecommunications operators that meet the evolving technology requirements of the wireless industry. These services include:

• Technology Interoperability Services. We operate one of the largest wireless data clearinghouses globally, enabling the accurate invoicing and settlement of domestic and global wireless roaming telephone calls and wireless data events. We also provide financial settlement services, Short Message Service (SMS), Multimedia Messaging Services (MMS) routing and translation, roaming fraud prevention services, interstandard

roaming solutions and Mobile Data Roaming (MDR) services between operators. In addition, we have expanded our mobile data solutions to include interactive video and mobile broadband solutions, prepaid applications and value-added roaming services. Wireless operators send data records to our service platforms for processing, aggregation, translation and distribution between operators.

• Network Services. We connect disparate wireless and fixed line operator networks and enable access to intelligent network database services like caller ID and provide translation and routing services to support the establishment and delivery of telephone calls through our SS7 hub. SS7

is the telecommunications industry’s standard network signaling protocol used by substantially all operators to enable critical telecommunications functions such as number portability, toll-free calling services and caller ID.

• Number Portability Services. Our leading number portability services are used by many wireless operators, including most domestic operators, to enable wireless subscribers to switch service providers while keeping the same telephone number. We also provide these services to all wireless operators in Canada and Singapore.

• Call Processing Services. We provide wireless operators with global call handling, signaling and fraud management solutions that enable

wireless subscribers from one operator to make and accept telephone calls while roaming on another operator’s network.

• Enterprise Solutions. Our enterprise wireless data management platform enables operators to offer large corporate customers reporting and

analysis tools to manage telecom-related expenses.

• Off-Network Database Queries. We provide our customers with the ability to connect to various third-party intelligent network database providers. These providers charge us a per-transaction fee for access to their databases, which we pass on to our customers with little or no margin.

Executive Overview Financial Highlights For the year ended December 31, 2008, total revenue increased $128.8 million, or 34.1%, to $506.4 million from $377.5 million for the year ended December 31, 2007. The increase in revenues was primarily due to organic volume growth in our Technology Interoperability services, primarily related to our MDR offering and increase in messaging, and our acquisition of BSG Wireless in December 2007. Net income increased $26.0 million, or 49.7%, to $78.5 million for the year ended December 31, 2008 from $52.4 million for the year ended December 31, 2007. Diluted earnings per share increased $0.37 to $1.15 for the year ended December 31, 2008 from $0.78 for the year ended December 31, 2007. Technology Interoperability services revenues increased $133.2 million, or 72.2%, to $317.7 million for the year ended December 31, 2008 compared to $184.5 million for the year ended December 31, 2007. The increase in revenues includes $54.9 million of revenues attributable to BSG Wireless, which was included in our income statement beginning on January 1, 2008. Excluding revenues from BSG Wireless, Technology Interoperability revenue grew 42.5%, driven by increases in data clearinghouse services, SMS and MMS interoperability, MDR services and UniRoam®. Number Portability services revenues increased $2.2 million, or 8.0%, to $29.3 million

36 Table of Contents for the year ended December 31, 2008 from $27.1 million for the year ended December 31, 2007. Revenues from Network services, Call Processing services, Enterprise Solutions and Off-Network Data Base Queries decreased a total of $6.5 million for the year ended December 31, 2008 compared to 2007.

During 2008, there were several developments that we expect will impact our growth rates in 2009, refer to “Business Developments” below. Accordingly, we expect our 2009 revenue, excluding Off-Network Database Queries, to be between $460 and $480 million. We expect net income to be between $64.5 and $74 million. We believe the current economic climate will have a mild, but noticeable impact on our roaming business, which is about 60% of our total business. This includes products like our roaming clearinghouse, mobile data roaming, Uniroam, Signaling Solutions and others.

Acquisitions We did not make any acquisitions during the year ended December 31, 2008.

On December 19, 2007, we acquired the wireless data clearing and financial settlement business (BSG Wireless) of Billing Services Group Limited (BSG) pursuant to a Share Purchase Agreement, dated April 1, 2007. Under the Purchase Agreement, we acquired all of the outstanding share capital of Billing Services Group S. à r.l. and Billing Services Group Asia Limited from BSG for an aggregate purchase price of $294.4 million in cash, which included debt repaid at closing and acquisition related costs of $7.4 million. The acquisition was funded through the draw down of our amended and restated credit facility, which included a delayed draw term loan of $160.0 million in aggregate principal amount and a Euro-denominated delayed draw term loan facility of the equivalent of $130.0 million intended to finance this acquisition. The acquisition allows us to combine our industry-leading technology interoperability and network services capabilities with BSG Wireless’ GSM data clearing expertise, European, Middle Eastern and Asian operator relationships, and financial clearing and settlement capabilities.

On June 16, 2006, we acquired the capital stock of Perfect Profits International, which comprises the Interactive Technologies Holdings Limited business (ITHL), from Interactive Technologies Holdings Limited for $45.7 million in cash including $1.1 million in acquisition related costs and working capital adjustments and earn-out to the sellers of $6.9 million, which was paid in April 2007. Headquartered in Hong Kong, ITHL is a leading provider of value-added services to operators in the Asia Pacific region. The acquisition expanded our footprint in the Asia Pacific region and added a complementary customer base, new products, advanced development capabilities and in-region customer support.

New Products In September 2008, we announced we are working with Colibria to develop an Advanced Messaging Hub solution. This solution, named Syniverse NEXT, provides interworking between operators for the exchange of presence data, instant messaging (IM), SMS, and MMS messages across networks, protocols and message types. Operators will be able to offer their subscribers more interactive, intuitive and convenient presence-based messaging services, and give those subscribers the ability to spontaneously communicate and share experiences with individuals, groups and social networking communities. We have structured our agreement with Colibria as a joint development agreement where we each bring our core capabilities to develop a solution where we will own the intellectual property. We will be contributing $4.0 to $5.0 million in capital expenditures to this joint development effort with $2.1 million contributed in 2008.

In February 2009, we announced a portfolio of business intelligence solutions that enables mobile operators to optimize roaming services based on a real-time view of subscriber roaming behavior and network performance. Syniverse RoamWise, a forecasting tool, is the first product to be launched from the portfolio. This forecasting tool simplifies the management of roaming information and increases the efficiency of operator roaming departments by bringing together data from across diverse networks. The tool centralizes the analysis of historical and real-time roaming data, and builds a comprehensive picture of future roaming trends so that business decisions can be made rapidly and effectively.

In February 2009, we launched our IP Packet eXchange Network Transport solution (IPX) to help global operators keep up with increasing volumes while maintaining quality of service for subscribers. IPX provides operators access to a full suite of mobile data services via a single ubiquitous network while supporting emerging 3G Plus solutions. Via this global network solution, operators connect to a single network to utilize a full suite of wireless data services. This approach means operators can reduce costs by adding additional services or increasing capacity without needing to connect to additional networks.

Business Developments During 2008, there were several developments that we expect will impact our growth rates in 2009. These developments include the Verizon acquisition of Alltel, the Alltel/Sprint insourcing initiative and the renewal of the Verizon contract. Each of these developments is described below.

Verizon Acquisition of Alltel During the second quarter of 2008, Verizon Wireless (Verizon) announced that it would acquire Alltel Corporation (Alltel). Verizon completed its acquisition of Alltel in January 2009. The impact of the combination of these two customers on us ranges across a variety of services, which affect revenues we receive not only from Verizon and Alltel, but from other roaming partners as well. The revenue impact expected is dependent on Verizon’s integration schedule. Our revenue and net income expectations for 2009 include very specific integration assumptions. These assumptions concern roaming traffic between Verizon and Alltel and other roaming traffic where Verizon has coverage but where Alltel currently uses a different roaming partner. The assumptions highlighted above are based on the current and best information available to us and we can provide no assurance that the actual impact of this transaction will not be more or less than what is reflected in our 2009 revenue and net income expectations.

Alltel/Sprint Insourcing Initiative In order to manage the expense associated with the significant volume growth in mobile data, Alltel and Sprint have directly connected their IP backbone networks. Thus, they no longer use Syniverse as a third party intermediary to manage the connectivity and exchange of billing records between their mobile data roaming platforms beginning in January 2009. Our revenue and net income expectations for 2009 include the impact of this insourcing initiative from the January 2009 effective date.

Verizon Renewal Effective September 30, 2008, we have extended our contract with Verizon for three years. Verizon uses a large suite of services, for its data clearing and roaming operations – products such as MDR, data clearinghouse, Visibility, UniRoam and a number of other services. Verizon’s new terms and pricing remain transaction-based, primarily affecting Technology Interoperability Services.

Revenues Most of our revenues are transaction-based charges under long-term contracts, typically with terms averaging three years in duration. From time to time, if a contract expires and we have not previously negotiated a new contract or renewal with the customer, we continue to provide services on a month to month billing schedule under the terms of the expired contract as we negotiate new agreements or renewals. Most of the services and solutions we offer to our customers are based on applications, network connectivity and technology platforms owned and operated by us. We also generate revenues through the sale of software licenses, hardware and professional services. We generate our revenues through the sale of our technology interoperability services, network services, number portability services, call processing services, enterprise solutions and off-network database queries to telecommunications operators throughout the world. Generally, there is a slight increase in wireless roaming telephone usage and corresponding revenues in the high-travel months of our second and third fiscal quarters.

Future increases or decreases in revenues are dependent on many factors, such as industry subscriber growth, subscriber habits, and volume and pricing trends, with few of these factors known in advance. From time to time, specific events such as customer contract renewals at different terms, a customer contract termination, a customer’s decision to change technologies or to provide solutions in-house, or a consolidation of operators will be known to us and then we can estimate their impact on our revenues.

Costs and Expenses Our costs and expenses consist of cost of operations, sales and marketing, general and administrative and depreciation and amortization.

• Cost of operations includes data processing costs, network costs, facilities costs, hardware costs, licensing fees, personnel costs associated with

service implementation, training and customer care and off-network database query charges.

• Sales and marketing includes personnel costs, advertising costs, trade show costs and relationship marketing costs.

• General and administrative includes research and development expenses, a portion of the expenses associated with our facilities, business development expenses, and expenses for executive, finance, legal, human resources and other administrative departments and professional service fees relating to these functions. Our research and development expenses, which are primarily personnel, relate to technology creation,

enhancement and maintenance of new and existing services. Historically, most of these costs are expensed and recorded as general and administrative expenses. The capitalized portion, which is recorded as capitalized software costs, relates to costs incurred during the application development stage for the new service offerings and significant service enhancements.

• Depreciation and amortization relate primarily to our property and equipment including our SS7 network, infrastructure facilities related to

information management, capitalized software and other intangible assets recorded in purchase accounting.

Revenues Total revenues increased $128.8 million to $506.4 million for the year ended December 31, 2008 from $377.5 million for the same period in 2007. The increase in revenues was primarily due to growth in Technology Interoperability Services driven by organic volume growth in our wireless data clearinghouse services, SMS and MMS interoperability, MDR services and the addition of $54.9 million of revenues from BSG Wireless.

Technology Interoperability Services revenues increased $133.2 million to $317.7 million for the year ended December 31, 2008 from $184.5 million for the same period in 2007. The increase in revenues was primarily due to organic volume growth in our wireless data clearinghouse services, SMS and MMS interoperability, MDR and the addition of $54.9 million of revenues from BSG Wireless for the year ended December 31, 2008. Over time, we expect the average per-transaction fee for certain services to continue to decline as a result of our volume-based and service bundling pricing strategy for most of our offerings as well as competitive pricing pressure.

Network Services revenues decreased $2.3 million to $122.5 million for the year ended December 31, 2008 from $124.8 million for the same period in 2007. The decrease in revenues was primarily due to customer

40 Table of Contents migrations off our services platform partially offset by increases in our SS7 and data networking products. Over time, we expect the average per-transaction fee for certain services will continue to decline as a result of our volume-based and service bundling pricing strategy and competitive pricing pressures.

Number Portability Services revenues increased $2.2 million to $29.3 million for the year ended December 31, 2008 from $27.1 million for the same period in 2007. The increase was primarily driven by an increase in wireless porting volumes resulting from both specific promotions of certain significant wireless operators in the U.S. and other porting activities.

Call Processing Services revenues decreased $1.7 million to $29.7 million for the year ended December 31, 2008 from $31.4 million for the same period in 2007. The decrease in revenues was due to continued declines in our legacy fraud-related services and Signaling Solutions due to expected network migrations. We expect this decline to continue for our legacy fraud-related services.

Enterprise Solutions revenues decreased $1.7 million to $2.4 million for the year ended December 31, 2008 from $4.1 million for the same period in 2007. The decrease in revenues was primarily due to a lower number of subscribers on our enterprise wireless data management platform. We expect this decline to continue.

Off-Network Database Queries revenues decreased $0.9 million to $4.7 million for the year ended December 31, 2008 from $5.6 million for the same period in 2007. The decrease in revenues was primarily driven by customers moving to direct access and billing arrangements with third-party intelligent network database providers. We pass these off-network database query fees onto our customers, with little or no margin, based upon the charges we receive from the third-party database providers. We expect this decline to continue.

Costs and expenses Cost of operations increased $27.7 million to $165.2 million for the year ended December 31, 2008 from $137.5 million for the same period in 2007. The increase was primarily due to expenses incurred by BSG Wireless, increased performance compensation and higher data processing costs commensurate with higher revenues.

Sales and marketing expenses increased $14.9 million to $45.5 million for the year ended December 31, 2008 from $30.6 million for the same period in 2007. The increase was primarily due to higher employee-related expenses for our global expansion, increased performance compensation and expenses incurred by BSG Wireless.

General and administrative expenses increased $22.3 million to $79.2 million for the year ended December 31, 2008 from $56.9 million for the same period in 2007. The increase was primarily due to expenses incurred by BSG Wireless and increases in legal fees, travel, sales incentive and performance compensation commensurate with higher revenues and severance and relocation expenses associated with changes in our senior management team.

Depreciation and amortization expenses increased $12.4 million to $55.3 million for the year ended December 31, 2008 from $42.9 million for the same period in 2007. The increase was primarily due to additional amortization of acquired intangible assets from our acquisition of BSG Wireless. Included in our depreciation and amortization expense for the year ended December 31, 2008 and 2007 is approximately $28.7 million and $18.8 million, respectively, of amortization related to intangible assets recorded in purchase accounting due to acquisitions we made beginning with our February 2002 acquisition from Verizon through our December 2007 acquisition of BSG Wireless.

Restructuring expense was $2.2 million for the year ended December 31, 2007. In January 2007, we completed a restructuring plan resulting in the closure of our Oklahoma office, the elimination of certain executive positions, and the termination of 10 employees. As a result, we incurred $0.7 million in severance

41 Table of Contents related costs and $1.3 million in costs associated with the lease of our corporate aircraft. In June 2007, we committed to a restructuring plan affecting our technology development and support groups. We estimated that the plan would result in the elimination of 56 employees over the remainder of the year. As a result, we accrued $0.6 million in severance related costs. During the third and fourth quarter of 2007, we experienced a higher than expected level of attrition among the employees impacted by the offshoring plan resulting in a reduction of our severance liability of $0.4 million.

Other Interest income was $1.9 million and $2.0 million for the years ended December 31, 2008 and 2007, respectively. Interest income was primarily earned on outstanding cash balances.

Interest expense increased $11.6 million to $37.2 million for the year ended December 31, 2008 from $25.6 million for the same period in 2007. The increase was primarily due to higher outstanding debt resulting from the financing of our acquisition of BSG Wireless in December 2007.

Other, net increased $0.3 million to $(0.4) million for the year ended December 31, 2008 from $(0.1) million for the same period in 2007. The increase was primarily due to foreign currency transaction losses as a result of our global expansion.

Provision for income taxes increased $15.5 million to $46.8 million for the year ended December 31, 2008 from $31.3 million for the same period in 2007. The increase in income taxes was primarily due to higher income before taxes. Our effective tax rates for the years ended December 31, 2008 and 2007 was approximately 37.4%.

Revenues Total revenues increased $40.5 million to $377.5 million for the year ended December 31, 2007 from $337.0 million for 2006. Excluding Off-Network Database Queries, which decreased $2.5 million for the year ended December 31, 2007, total revenues increased $43.0 million for the year ended December 31, 2007. The increase in revenues was primarily due to increases in our Technology Interoperability Services and our Call Processing Services, offset in part by decreases in our Number Portability Services, Network Services, Enterprise Solutions and Off-Network Database Queries.

Technology Interoperability Services revenues increased $45.8 million to $184.5 million for the year ended December 31, 2007 from $138.7 million for 2006. The increase in revenues was primarily due to organic volume

43 Table of Contents growth in our wireless data clearinghouse services, SMS interoperability, mobile data roaming services and the addition of revenues from our acquisition of ITHL of $26.0 million for the year ended December 31, 2007 as compared to $17.7 million in 2006.

During the preparation of our 2006 annual financial statements, we discovered a customer billing error related to one of our services. As a result, we determined that our revenues were overstated during the period from October 2005 to September 2006 by $2.4 million, of which $0.1 million related to the fourth quarter of 2005. We reviewed the impact of the error on the fourth quarter of 2005 and through the third quarter of 2006 and concluded that the cumulative impact of the error was not material to the previously reported quarters. As a result, we recorded the full amount of the error in the fourth quarter of 2006.

Network Services revenues were $124.8 million for both the years ended December 31, 2007 and 2006. This reflects the migration off our services platform by certain customers and price concessions commensurate with our volume-based and service bundling pricing strategy for certain of our services and a competitive pricing environment. During 2006, two of our SS7 customers completed the process of replacing our SS7 network solution, resulting in a reduction of 2006 network services revenues by $6.3 million.

Number Portability Services revenues decreased $1.6 million to $27.1 million for the year ended December 31, 2007 from $28.8 million for 2006. The decrease in revenues was primarily due to lower port center activity in addition to price concessions from contract renewals concluded in late 2006 and early 2007, partially offset by revenue from new services offered to Canadian operators.

Call Processing Services revenues increased $2.1 million to $31.4 million for the year ended December 31, 2007 from $29.3 million for 2006. This increase primarily results from increased international roaming volumes driving increased demand for our Signaling Solutions services, offset by a reduction of our legacy fraud-related services.

Enterprise Solutions revenues decreased $3.2 million to $4.1 million for the year ended December 31, 2007 from $7.3 million for 2006. The decrease in revenues was primarily due to a lower number of subscribers on our enterprise wireless data management platform. We expect this decline to continue.

Off-Network Database Queries revenues decreased $2.5 million to $5.6 million for the year ended December 31, 2007 from $8.2 million for 2006. The decrease in revenues was primarily driven by customers moving to direct access and billing arrangements with third-party intelligent network database providers. We pass these off-network database query fees onto our customers, with little or no margin, based upon the charges we receive from the third-party database providers. We expect this decline to continue.

Expenses Cost of operations increased $2.9 million to $137.5 million for the year ended December 31, 2007 from $134.6 million for 2006. The increase was primarily due to ITHL cost of operations, partially offset by decreases in our off-network database queries services.

Sales and marketing expenses increased $5.2 million to $30.6 million for the year ended December 31, 2007 from $25.4 million for 2006. The increase was primarily due to expenses related to our global expansion in addition to increased performance-based compensation.

General and administrative expenses decreased $1.6 million to $56.9 million for the year ended December 31, 2007 from $58.5 million for 2006. The decrease was primarily due to $5.3 million of costs incurred during 2006 related to the relocation of our corporate headquarters, including $1.7 million associated with the early lease termination of our former corporate headquarters, offset in part by increases in general and administrative expenses related to ITHL (includes twelve months of general and administrative expenses for 2007 compared to six months of expenses in 2006) and higher performance-based and stock-based compensation expense.

Depreciation and amortization expenses increased $1.7 million to $42.9 million for the year ended December 31, 2007 from $41.2 million for 2006. The increase was primarily due to additional amortization of intangible assets from our acquisition of ITHL. Included in our depreciation and amortization expenses for the years ended December 31, 2007 and 2006 is approximately $18.8 million and $17.8 million, respectively, of amortization related to intangible assets recorded in purchase accounting due to our February 2002 acquisition from Verizon, our December 2003 acquisition of Syniverse Holdings Limited (formerly Softwright Holdings Limited), our September 2004 acquisition of IOS North America and our June 2006 acquisition of ITHL.

Restructuring expense was $2.2 million and $1.0 million for the years ended December 31, 2007 and 2006, respectively. In February 2006, we completed a restructuring plan in our marketing group resulting in the termination of 8 employees. As a result, we incurred $0.3 million in severance related costs. In August 2006, we completed a restructuring plan in our operations and marketing groups resulting in the termination of 30 employees. As a result, we incurred $0.7 million in severance related costs. In January 2007, we completed a restructuring plan resulting in the closure of our Oklahoma office, the elimination of certain executive positions, and the termination of 10 employees. As a result, we incurred $0.7 million in severance related costs and $1.3 million in costs associated with the termination of the lease of our corporate aircraft. In June 2007, we committed to a restructuring plan affecting our technology development and support groups. We estimated that the plan would result in the elimination of 56 employees over the remainder of the year. As a result, we accrued $0.6 million in severance related costs. During the third and fourth quarter of 2007, we experienced a higher than expected level of attrition among the employees impacted by the offshoring plan, resulting in a reduction of our severance liability of $0.4 million.

Other Interest income increased $0.2 million to $2.0 million for the year ended December 31, 2007 from $1.8 million for 2006 primarily due to interest income earned on higher outstanding cash balances.

Interest expense decreased $1.7 million to $25.6 million for the year ended December 31, 2007 from $27.3 million for 2006. The decrease was primarily due to lower outstanding debt balances.

Loss on extinguishment of debt was $0.9 million for the year ended December 31, 2006. In February 2006, we redeemed all of our outstanding 12 3/4% senior subordinated notes due 2009 resulting in a prepayment premium of $0.9 million.

Other, net was $(0.1) million for the year ended December 31, 2007 and $0.3 million for the year ended December 31, 2006, and is comprised of non- operating revenues and expenses.

Provision for income taxes was $31.3 million for the year ended December 31, 2007. Benefit from income taxes was $39.6 million for the year ended December 31, 2006. During the year ended December 31, 2006, we reversed a significant portion of our net deferred tax asset valuation allowance. The valuation allowance, originally established in 2003 and adjusted annually thereafter, was recorded because the realization of those deferred tax assets did not meet the more-likely-than-not criteria under Statement of Financial Accounting Standards No. 109, Accounting for Income Taxes (SFAS 109). In the fourth quarter of 2006, based upon an evaluation of our most recent seven quarters of profitability and our expectations of continued net income, a tax benefit for the deferred tax assets was recognized as we determined that we have met the more-likely-than not criteria related to those deferred tax assets. The benefit reduced our estimated 2006 annual effective tax rate to approximately (78.9)%. For the year ended December 31, 2007, our annual effective tax rate was 37.4%. As of December 31, 2007, based upon our judgment, we will continue to maintain a valuation allowance for certain other deferred tax assets primarily associated with foreign and state net operating loss carry-forwards and capital loss carry forwards.

Liquidity and Capital Resources Cash Flow Information The following table sets forth, for the periods indicated, selected consolidated cash flow information (in thousands).

Year Ended December 31, 2008 2007 2006 Net cash provided by operating activities $163,972 $ 121,262 $ 97,811 Net cash used in investing activities (41,642) (301,953) (63,683) Net cash provided by (used) in financing activities (903) 202,275 (57,052) Effect of exchange rate changes on cash (4,908) 798 334 Net increase (decrease) in cash $116,519 $ 22,382 $(22,590)

Net cash provided by operating activities was $164.0 million for the year ended December 31, 2008 as compared to $121.3 million for the same period in 2007. The increase was primarily related to higher net income adjusted for non-cash items (depreciation and amortization, provision for uncollectible accounts, deferred income tax expense, stock-based compensation, and loss on disposition of property) and changes in operating assets and liabilities. Cash and cash equivalents were $165.6 million at December 31, 2008 as compared to $49.1 million at December 31, 2007. This increase was primarily due to an increase in net cash provided by operating activities, partially offset by principal payments on our senior credit facility and higher capital expenditures. Our working capital increased $122.0 million to $196.2 million at December 31, 2008 from $74.2 million at December 31, 2007 primarily due to higher net cash from operating activities partially offset by higher accrued liabilities.

Net cash used in investing activities was $41.6 million for the year ended December 31, 2008, which includes $40.8 million for capital expenditures and $0.8 million for the acquisition of BSG Wireless. Net cash used in investing activities was $302.0 million for the year ended December 31, 2007, which includes $273.6 million, net of acquired cash, for the acquisition of BSG Wireless and $27.7 million for capital expenditures. Net cash used in investing activities was $63.7 million for the year ended December 31, 2006, which includes $43.9 million, net of acquired cash, for the acquisition of ITHL and $19.9 million of capital expenditures. Capital expenditures for property and equipment, including capitalized software costs, increased $13.1 million to $40.8 million for the year ended December 31, 2008 from $27.7 million for the same period in 2007. For the year ended December 31, 2008 we incurred approximately $40.8 million for capital expenditures primarily for network infrastructure to support customer growth, non-network production upgrades and capitalized software. Capital expenditures for property and equipment, including capitalized software costs, increased $7.8 million to $27.7 million for the year ended December 31, 2007 from $19.9 million for the same period in 2006. For the year ended December 31, 2007 we incurred approximately $27.7 million for capital expenditures primarily for non-network production upgrades, investment in our messaging infrastructure to support our anticipated growth and capitalized software development. For the year ended December 31, 2006, we incurred approximately $19.9 million for capital expenditures, primarily for investment in our network, capital expenditures associated with our lease of new office space and capitalized software development. We expect total capital expenditures in 2009 to be approximately 7.5% of revenues (excluding Off-Network Database Queries) compared to 8.1% in 2008. Net cash used in financing activities was $0.9 million for the year ended December 31, 2008, which includes principal payments on our senior credit facility of $3.5 million offset by $2.6 million issuances of stock related to stock-based compensation. Net cash provided by financing activities was $202.3 million for the year ended December 31, 2007, which includes $290.0 million of borrowings to fund our acquisition of BSG Wireless partially offset by principal payments on our senior credit facility of $81.6 million and debt issuance costs paid in connection with our amended and restated credit facility of $7.2 million. Net cash used in financing activities was $57.1 million for the year ended December 31, 2006, which includes $41.7 million of principal payments on our senior credit facility and $15.4 million for the repayment of our 12 3/4% senior subordinated notes due 2009.

In 2008, Lehman Commercial Paper Inc. (Lehman CPI) filed a petition under Chapter 11 of the U.S. Bankruptcy Code with the U.S. Bankruptcy Court for the Southern District of New York. Lehman CPI is the administrative agent of our senior credit facility. Lehman CPI has $28.2 million (45.5 percent) of the $62.0 million in commitments under our undrawn revolving credit line. It is doubtful Lehman CPI will honor its obligations under the revolving credit line.

On October 6, 2008, we entered into an interest rate swap agreement to hedge $100.0 million of our U.S.-denominated term loan under our senior credit facility. The hedge effectively swaps variable rate interest expense based on 1-month LIBOR to a fixed rate interest expense thereby reducing our exposure to interest rate fluctuations. The effective date of the swap is October 31, 2008 and the maturity date is October 31, 2010. The fixed rate is 5.26% based on our 2.76% swap rate plus our 2.50% applicable margin.

Our principal sources of liquidity are cash flows generated from operations and borrowings under our senior credit facility. Our principal uses of cash are to meet debt service requirements, finance our capital expenditures, make acquisitions and provide working capital. We expect that cash on hand, cash available from operations, and the availability of cash under our revolving line of credit will be sufficient to fund our operations, debt service and capital expenditures for the foreseeable future.

Debt and Credit Facilities Amended and Restated Senior Credit Facility On August 9, 2007, we entered into a $464.0 million amended and restated credit agreement, the senior credit facility, with Lehman Brothers Inc. and Deutsche Bank Securities Inc. as joint lead arrangers and joint book-running managers, Lehman Commercial Paper Inc., as administrative agent, Deutsche Bank AG New York Branch, as syndication agent, Bear Stearns Corporate Lending Inc. and LaSalle Bank National Association, as co-documentation agents and the lenders from time to time parties thereto. The obligations under the senior credit facility are unconditionally guaranteed by Syniverse Holdings, Inc. and all material U.S. domestic subsidiaries of Syniverse Technologies, Inc. (the “Guarantors”) and are secured by a security interest in substantially all of the tangible and intangible assets of Syniverse Technologies, Inc. and the Guarantors. The obligations under the senior credit facility are also secured by a pledge of the capital stock of Syniverse Technologies, Inc. and its direct and indirect U.S. subsidiaries.

The senior credit facility provides for aggregate borrowings of $464.0 million as follows:

• a term loan of $112.0 million in aggregate principal amount;

• a delayed draw term loan of $160.0 million in aggregate principal;

• a Euro-denominated delayed draw term loan facility of the equivalent of $130.0 million;

• a revolving credit line of $42.0 million; and

• a Euro-denominated revolving credit line of the equivalent of $20.0 million.

On December 19, 2007, the delayed draw term loans of $290.0 million (delayed draw term loan of $160.0 million and Euro-denominated delayed draw term loan of the equivalent of $130.0 million) were used to fund the acquisition of the BSG Wireless described in Note 5 of our consolidated financial statements, including the repayment of existing debt and to pay related transaction fees and expenses. The delayed draw term loans were subject to a commitment fee of 1.25% per annum on undrawn amounts.

The applicable margin for the base rate term loan and the base rate revolving loans is 1.50%. U.S. dollar denominated borrowings bear interest at either a base rate or, at our option, a LIBOR rate. The applicable margin for the Eurodollar term loan, Euro-denominated term loan and Eurodollar revolving loans is 2.50%. Euro-denominated borrowings under the senior credit facility bear interest at a EURIBOR rate. The term loan facilities

47 Table of Contents require regularly scheduled quarterly payments of principal and interest, and the entire amount of the term loan facilities will mature on August 9, 2014. The full amount borrowed under the revolving credit line will mature on August 9, 2013. In the event we fail to refinance our 7 3/4% senior subordinated notes by February 15, 2013, then the maturity date of our term loan facilities and revolving credit line will be accelerated to February 15, 2013.

As of December 31, 2008, we had an aggregate face amount of $338.8 million of outstanding indebtedness under our senior credit facility representing $213.2 million in U.S. dollar denominated term loans, $125.6 million in Euro-denominated term loans, $42.0 million available under the revolving credit facility and $18.1 million available under the Euro-denominated revolving credit line. As of December 31, 2008, the applicable interest rate was 2.97% on the term loan based on the LIBOR option and 5.2% on the Euro-denominated delayed term loan based on the EURIBOR option.

The senior credit facility contains covenants that will limit our ability and that of our Guarantors to, among other things, incur or guarantee additional indebtedness, create liens, pay dividends on or repurchase stock, make certain types of investments, restrict dividends or other payments from our subsidiaries, enter into transactions with affiliates and sell assets or merge with other companies. The senior credit facility also requires compliance with financial covenants, including a maximum ratio of total indebtedness to Consolidated EBITDA. As of December 31, 2008, we believe we are in compliance with all of our covenants contained in the senior credit facility.

7 3/4% Senior Subordinated Notes Due 2013

On August 24, 2005, we completed a private offering of $175.0 million in aggregate principal amount of our 7 3/4% senior subordinated notes due 2013. Interest on the notes accrues at the rate of 7 3/4% per annum and is payable semi-annually in arrears on February 15 and August 15, commencing on February 15, 2006.

The indenture governing our 7 3/4% senior subordinated notes due 2013 contains certain covenants that among other things, limit our ability to incur additional indebtedness and issue preferred stock, pay dividends, make other restricted payments and investments, create liens, incur restrictions on the ability of our subsidiaries to pay dividends or other payments to them, sell assets, merge or consolidate with other entities, and enter into transactions with affiliates. As of December 31, 2008, we believe we are in compliance with all of the covenants contained in the indenture governing our senior subordinated notes.

12 3/4% Senior Subordinated Notes due 2009 On February 1, 2006, Syniverse completed an early redemption for all remaining notes of $14,500 in aggregate principal amount of its outstanding 12 3/4% Senior Subordinated Notes due 2009 at a premium of $924.

Effect of Inflation Inflation generally affects us by increasing our cost of labor, equipment and new materials. We do not believe that inflation has had any material effect on our results of operations during the years ended December 31, 2008 and 2007.

Critical Accounting Policies and Estimates The preparation of our financial statements in conformity with accounting principles generally accepted in the United States requires us to make estimates and judgments that affect our reported amounts of assets and liabilities, revenues and expenses. We consider an accounting estimate to be critical if it requires assumptions to be made that were uncertain at the time the estimate was made and changes in the estimate or different estimates that could have been selected could have a material impact on our consolidated results of operations or financial condition. We have identified the following critical accounting policies that affect the more significant estimates and judgments.

48 Table of Contents

Revenue Recognition We derive revenues from six categories: Technology Interoperability Services, Network Services, Number Portability Services, Call Processing Services, Enterprise Solutions and Off-Network Database Queries. The revenue recognition policy for each of these areas is described in Note 2 of Notes to Consolidated Financial Statements contained in this report.

Allowance for Doubtful Accounts We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to pay their invoices to us in full. We regularly review the adequacy of our accounts receivable allowance after considering the size of the accounts receivable balance, each customer’s expected ability to pay and our collection history with each customer. A portion of this analysis is dependent on our ability to gather reliable information about our customers’ specific circumstances. As part of our analysis, we review significant invoices that are past due to determine if an allowance is necessary based on the risk category using the factors described above. Based on the circumstances, we place each customer into a risk category and assign allowance percentages between 5% and 100%. Our estimates of allowances for doubtful accounts have tracked well with our actual experience of customers who are unable to pay their invoices in full. However, uncollectible accounts that are not identified or properly assessed in our review could have a significant impact on our bad debt provision. In addition, if our customers’ financial condition or the economy in general deteriorates, we may need to increase these allowances for doubtful accounts. Excluding all risk categories that are reserved at 100%, a 10% change in each one of our risk categories would cause our allowance for doubtful accounts as of December 31, 2008 and our bad debt expense for the year then ended to change by $0.1 million. Because we perform our analysis and establish our allowance for doubtful accounts on a customer-by-customer basis, we generally do not record a reserve for unknown factors. However, if we were to apply a reserve for unknown factors of 1% to our unreserved accounts receivable balance, it would increase our allowance for doubtful accounts as of December 31, 2008 and our bad debt expense for the year then ended by approximately $0.8 million

Allowance for Credit Memos We maintain an allowance for credit memos based on our historical credit memo activity. In addition, we establish allowances for credit memos resulting from specific customer matters. This allowance is recorded as a direct reduction of accounts receivable and revenues. Since our allowances for credit memos are derived in large part from specific customer matters, our estimates have tracked well with our actual credit memo experience. If our billing errors or discrepancies are not resolved satisfactorily or our customers’ disputes over billing are not resolved satisfactorily, increases to the allowance would be required. As of December 31, 2008, our allowance for credit memos totaled $1.6 million. If our allowance for credit memos, including identified specific customer matters, changed by 10%, our allowance for credit memos and revenues would change by approximately $0.2 million.

Impairment Losses on Long-Lived Assets We review our long-lived assets, including property and equipment and intangibles with definite lives for impairment when events or changes in circumstances indicate the carrying value of such assets may not be recoverable. We also evaluate the useful life of our assets each reporting period, and if deemed to be shorter than originally estimated, would result in an increase in our annual depreciation and/or amortization expense.

If an impairment indicator existed, we would perform a comparison of the carrying value of the assets with the assets’ expected future undiscounted cash flows without interest costs. An impairment loss is recognized if the carrying amount of a long-lived asset is not recoverable and exceeds its fair value. The carrying amount of a long-lived asset is deemed to not be recoverable if it exceeds the sum of its undiscounted cash flows. Estimates of expected future cash flows are management’s best estimate based on reasonable and supportable assumptions

49 Table of Contents and projections. If actual market conditions are less favorable than those projected by management, asset impairment charges may be required. Management continues to evaluate overall industry and company-specific circumstances and conditions to identify indicators of impairment. No impairment was recognized for the year ended December 31, 2008.

Impairment Losses on Goodwill We evaluate goodwill for impairment at least annually, or more frequently if indicators of impairment arise, in accordance with the provisions of Statement of Financial Accounting Standards No. 142, Goodwill and Other Intangible Assets (SFAS 142). Our evaluation of goodwill is measured by a two- step impairment test. The first step compares the fair value of our reporting unit with its carrying amount, including goodwill. If the carrying amount of our reporting unit exceeds its fair value, we then compare the implied fair value of the reporting unit’s goodwill with the carrying amount of that goodwill. An impairment loss would be recognized to the extent that the carrying amount of the reporting unit’s goodwill exceeds the implied fair value of that goodwill. Estimates are based on reasonable and supportable assumptions and projections. If actual market conditions are less favorable than those projected by management, an impairment loss may be required to be recognized. Management will continue to evaluate overall industry and company-specific circumstances and conditions as necessary. No impairment was recognized for the year ended December 31, 2008.

Recent Accounting Pronouncements In September 2006, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157). SFAS 157 clarifies the principle that fair value should be based on the assumptions market participants would use when pricing an asset or liability and establishes a fair value hierarchy that prioritizes the information used to develop those assumptions. Under the standard, fair value measurements are separately disclosed by level within the fair value hierarchy. SFAS 157 is effective January 1, 2008. On February 12, 2008, the FASB issued FASB Staff Position (FSP) 157-2 which delays the effective date of SFAS No. 157 for one year, for all non financial assets and non financial liabilities, except those that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually). SFAS No. 157 and FSP 157-2 were effective for us beginning January 1, 2008. The partial adoption of SFAS 157 did not have a material impact on our financial position or results of operations.

In February 2007, the FASB issued Statement of Financial Accounting Standards No. 159, The Fair Value Option for Financial Assets and Financial Liabilities—Including an Amendment of FASB Statement No. 115 (SFAS 159). This standard permits an entity to choose to measure many financial instruments and certain other items at fair value. The fair value option permits a company to choose to measure eligible items at fair value at specified election dates. A company will report unrealized gains and losses on items for which the fair value option has been elected in earnings after adoption. SFAS 159 was effective for us beginning on January 1, 2008. The adoption of SFAS 159 did not have a material impact on our financial position or results of operations and we did not elect to measure eligible items at fair value under this Statement.

In December 2007, the FASB issued Statement of Financial Accounting Standards No. 141 (revised 2007), Business Combinations (SFAS 141R). SFAS 141R provides revised guidance on how acquirers recognize and measure the consideration transferred, identifiable assets acquired, liabilities assumed, noncontrolling interests, and goodwill acquired in a business combination. SFAS 141R also expands required disclosures surrounding the nature and financial effects of business combinations. SFAS 141R is effective, on a prospective basis, for fiscal years beginning after December 15, 2008. The adoption of SFAS 141R will not have a material impact on our financial position and results of operations.

Contractual Obligations and Commitments As of December 31, 2008, our contractual obligations consist of our debt, operating leases equipment and service contracts and pension plan liabilities associated with our acquisition of BSG Wireless.

Less Than 1 1 to 3 3 to 5 More Than 5 Contractual Obligations Total Year Years Years Years (dollars in thousands) Long-term debt obligations including interest (1) $651,105 $ 32,086 $61,106 $228,588 $ 329,325 Operating lease obligations 42,216 7,540 11,368 9,651 13,657 Purchase obligations (2) 3,619 1,872 1,747 — — Pension obligation (3) 958 8 37 85 828 Total $697,898 $ 41,506 $74,258 $238,324 $ 343,810

(1) The interest rate on the term loans is at 2.5% plus LIBOR for the U.S. denominated portion and 2.5% plus EURIBOR for the Euro-denominated portion, with LIBOR assumed to be 0.47% and EURIBOR assumed to be 2.70%. (2) Amounts represent primarily purchase obligations for equipment and services. Certain of these obligations represent fees that we would incur if we were to cancel or terminate the underlying purchase agreement. (3) Represents estimated obligations from a noncontributory defined benefit retirement plan assumed by us as part of the acquisition of BSG Wireless

Off-Balance Sheet Arrangements We provide financial settlement services to wireless operators to support the payment of roaming related charges to their roaming network partners. In accordance with our contract with the customer, funds are held by us as an agent on behalf of our customers to settle their roaming related charges to other operators. These funds and the corresponding liability are not reflected in our consolidated balance sheet. The off-balance sheet amounts totaled approximately $101.3 million and $88.0 million as of December 31, 2008 and 2007, respectively.

We have also used off-balance sheet financing in recent years primarily in the form of operating leases for facility space and some equipment leasing and we expect to continue these practices. We do not use any other type of joint venture or special purpose entities that would create off-balance sheet financing. We believe that our decision to lease our office space is similar to that used by many other companies of our size and does not have a material impact to our financial statements.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK Interest Rate Market Risk We are exposed to changes in interest rates on our senior credit facility. Our senior credit facility is variable rate debt. Interest rate changes therefore generally do not affect the market value of such debt but do impact the amount of our interest payments and, therefore, our future earnings and cash flows, assuming other factors are held constant. As of December 31, 2008 and December 31, 2007, we had $338.8 million and $347.9 million, respectively, of variable rate debt outstanding on our senior credit facility. Holding other variables constant, including levels of indebtedness, a one percentage point increase in interest rates on our variable debt would have had an estimated impact on pre-tax earnings and cash flows for the next year of approximately $3.4 million. Under the terms of the senior credit facility at least 25% of our funded debt must bear interest that is effectively fixed. As a result, we may from time to time be required to enter into interest rate protection agreements establishing a fixed maximum interest rate with respect to a portion of our total indebtedness.

51 Table of Contents

On October 6, 2008, we entered into an agreement to hedge $100.0 million of our U.S.-denominated term loan under our senior credit facility. The hedge effectively swaps variable rate interest expense based on 1-month LIBOR to a fixed rate interest expense thereby reducing our exposure to interest rate fluctuations. The effective date of the swap is October 31, 2008 and the maturity date is October 31, 2010. The fixed rate is 5.26% based on our 2.76% swap rate plus our 2.50% applicable margin.

Foreign Currency Market Risk Although the majority of our operations are conducted in United States dollars, our significant foreign operations are conducted in Euros and Great Britain Pounds. Our exposure to these currencies is the result of our acquisition of BSG Wireless in December 2007, thus the impact of changes in the foreign currency exchange rates on our revenue and net income for the year ended December 31, 2008 compared to the year ended December 31, 2007 is not significant. On a less significant basis, we conduct operations in the various currencies of the Asia-Pacific region, Canada and Latin America, several of which are directly tied to the movement in the United States dollar. Consequently, a portion of our revenues and expenses may be affected by fluctuations in foreign currency exchange rates. We are also affected by fluctuations in exchange rates on assets and liabilities related to our foreign operations. We have not hedged our translation risk on foreign currency exposure through the use of derivative instruments.

A 10% change in average foreign currency rates against the United States dollar during the year ended December 31, 2008 compared to the average foreign currency exchange rates during the year would have increased or decreased our revenues and net income by approximately $7.1 million and $2.9 million, respectively.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA Our financial statements required by this item are set forth as a separate section of this Annual Report on Form 10-K. See page 60 for an index to our “Consolidated Financial Statements”, which are incorporated by reference here in.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE Not applicable.

ITEM 9A. CONTROLS AND PROCEDURES Evaluation of Disclosure Controls Our management, including our principal executive officer and principal financial officer, concluded an evaluation of the effectiveness of our disclosure controls and procedures as of December 31, 2008. Our evaluation tested controls and other procedures designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934, as amended, or the Exchange Act, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Based on our evaluation, as of December 31, 2008, our management, including our principal executive officer and principal financial officer, concluded that our disclosure controls and procedures were effective.

Changes in Internal Control Over Financial Reporting There were no changes in our internal control over financial reporting during our most recently completed fiscal quarter that have materially affected or are reasonably likely to materially affect our internal control over financial reporting.

Management’s Report on Internal Control Over Financial Reporting Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in the Exchange Act Rules13a-15(f). Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures are being made only with proper authorizations; and (3) provide reasonable assurance regarding prevention of timely detection of unauthorized acquisition, use, or disposition of our assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Under the supervision and with the participation of management, including our principal executive officer and principal financial officer, our management has evaluated the effectiveness of our internal control over financial reporting as of December 31, 2008 based on the criteria established in a report entitled Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission, or COSO. Based on its assessment, management concluded that we maintained effective internal control over financial reporting as of December 31, 2008.

The effectiveness of internal control over financial reporting as of December 31, 2008 has been audited by Ernst & Young, LLP, the independent registered certified public accounting firm who also audited the Company’s consolidated financial statements, as stated in their report below.

Report of Independent Registered Certified Public Accounting Firm

The Board of Directors and Stockholders of Syniverse Holdings, Inc. We have audited Syniverse Holdings, Inc.’s internal control over financial reporting as of December 31, 2008, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Syniverse Holdings, Inc.’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Syniverse Holdings, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2008, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets as of December 31, 2008 and 2007, and the related consolidated statements of income, changes in stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2008 of Syniverse Holdings, Inc. and our report dated February 26, 2009 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED CERTIFIED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders of Syniverse Holdings, Inc. We have audited the accompanying consolidated balance sheets of Syniverse Holdings, Inc. as of December 31, 2008 and 2007, and the related consolidated statements of income, changes in stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2008. Our audits also included the financial statement schedule listed in the index at Item 15(a). These financial statements and schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Syniverse Holdings, Inc. at December 31, 2008 and 2007, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2008, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Syniverse Holdings, Inc.’s internal control over financial reporting as of December 31, 2008, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 26, 2009, expressed an unqualified opinion thereon.

SYNIVERSE HOLDINGS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (AMOUNTS IN THOUSANDS EXCEPT SHARE AND PER SHARE DATA)

1. Description of Business We are a leading enabler of wireless voice and data services for telecommunications companies worldwide. We were incorporated in Delaware on November 9, 2001 and we completed our initial public offering on February 10, 2005. For over 20 years, including our time as part of our former parent company, we have served as one of the wireless industry’s only operator-neutral intermediaries, solving the challenges that arise as new technologies, standards and protocols emerge. Our data clearinghouse, network and technology services solve technical and operational challenges for the wireless industry by translating incompatible communication standards and protocols and simplifying operator interconnectivity. Our suite of transaction-based services allows operators to deliver seamless voice, data and next generation services to wireless subscribers, including wireless voice and data roaming, Short Message Service (SMS), Multimedia Messaging Services (MMS), Mobile Instant Messaging (MIM), number portability and wireless vaule-added services. We currently provide our services to more than 650 operators in over 140 countries.

2. Summary of Significant Accounting Policies Basis of Presentation and Principles of Consolidation The consolidated financial statements include our accounts and our subsidiaries. These consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States and present our financial position, results of operations and cash flows. All significant intercompany balances and transactions have been eliminated.

Use of Estimates We prepare our financial statements using accounting principles generally accepted in the United States, which require management to make estimates and assumptions that affect reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, as well as the reported revenues and expenses during the period. Actual results could differ from those estimates.

Revenue Recognition The majority of our revenues are transaction-based charges under long-term contracts, typically averaging three years in duration. From time to time, if a contract expires and we have not previously negotiated a new contract or renewal with the customer, we continue to provide services under the terms of the expired contract on a month-to-month billing schedule as we negotiate new agreements or renewals. Our revenues are primarily the result of the sale of our technology interoperability services, network services, number portability services, call processing services, enterprise solutions and off-network database queries to wireless operators throughout the world. Generally, there is a seasonal increase in wireless roaming telephone usage and corresponding revenues in the high-travel months of our second and third fiscal quarters.

• Technology Interoperability Services primarily generate revenues by charging per-transaction processing fees. For our wireless roaming clearinghouse, SMS services, MMS services, DataNet services, interstandard roaming solutions and Mobile Data Roaming (MDR) services, revenues vary based on the number or size of data/messaging records provided to us by wireless operators for aggregation, translation and distribution among operators. We recognize revenues at the time the transactions are processed. For our financial clearinghouse and settlement services, revenues vary based on the number of invoices or roaming agreements managed on the customer’s behalf. We recognize revenues at the time the transactions are processed. Additionally, we provide solutions with multiple product and service elements which may include software and hardware products, as well as

66 Table of Contents

installation services, post-contract customer support and training. In those cases, we recognize revenues in accordance with the American Institute of Certified Public Accountants’ Statement of Position 97-2 (SOP 97-2), Software Revenue Recognition, as amended by SOP 98-9, Modification of SOP 97-2, Software Revenue Recognition With Respect to Certain Transactions. Under SOP 97-2, revenue attributable to an element in a customer arrangement is recognized when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable and collectability is probable.

• Network Services primarily generate revenues by charging per-transaction processing fees. In addition, our customers pay monthly connection fees based on the number of network connections as well as the number of switches with which a customer communicates. The per-transaction

fees are based on the number of intelligent network messages and intelligent network database queries made through our network and are recognized as revenues at the time the transactions are processed.

• Number Portability Services primarily generate revenues by charging per-transaction processing fees, monthly fixed fees, and fees for customer implementations. We recognize processing revenues at the time the transactions are processed. We recognize monthly fixed fees as revenues on a

monthly basis as the services are performed. We defer revenues and incremental customer-specific costs related to customer implementations and recognize these fees and costs on a straight-line basis over the life of the initial customer agreements.

• Call Processing Services primarily generate revenues by charging per-transaction processing fees. The per-transaction fee is based on the number of validation, authorization and other call processing messages generated by wireless subscribers. We recognize processing fee revenues at the time the transactions are processed.

• Enterprise Solutions primarily generate revenues by charging per-subscriber fees. We recognize these revenues at the time the service is

performed.

• Off-Network Database Queries primarily generate revenues by providing access to database providers. We pass these charges onto our customers, with little or no margin, based upon the charges we receive from the third party intelligent network database providers. We recognize revenues at the time the transactions are processed.

Research and Development Research and development costs are charged to expense as incurred. Research and development costs which are included in general and administrative expense in the consolidated statements of income amounted to $9,703, $5,987 and $5,518 for the years ended December 31, 2008, 2007 and 2006, respectively.

Stock-Based Compensation On May 16, 2002, Syniverse Inc.’s Board of Directors adopted a Founders’ Stock Option Plan for non-employee directors, executives and other key employees and a Directors’ Stock Option Plan for directors. On May 9, 2006, our Board of Directors adopted the 2006 Long-Term Equity Incentive Plan and Employee Stock Purchase Plan. We account for these plans and related grants thereunder using the fair value based method under Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payment (SFAS 123(R)). Please refer to Note 6 for further discussion regarding stock-based compensation.

67 Table of Contents

Cash and Cash Equivalents We consider all highly liquid investments of operating cash with original maturities of three months or less to be a cash or cash equivalent. Cash and cash equivalents include money market funds and various deposit accounts and are stated at cost, which approximates fair value.

Customer Accounts We provide financial settlement services to wireless operators to support the payment of roaming related charges to their roaming network partners. In accordance with our contract with the customer, funds are held by us as an agent on behalf of our customers to settle their roaming related charges to other operators. These funds and the corresponding liability are not reflected in our consolidated balance sheet. The off-balance sheet amounts totaled approximately $101,311 and $87,977 as of December 31, 2008 and 2007, respectively.

During the financial settlement process, customer funds may be held by us due to the time taken to clear transactions with our customers’ roaming partners. These funds are treated as a receivable and a corresponding payable until the funds are settled. As of December 31, 2008, the balance in these accounts was $6,082 and is included “Prepaid and other current assets” and “Other accrued liabilities” in our consolidated balance sheet.

Accounts Receivable Accounts receivable are recorded at net realizable value which is the amount that we expect to collect on our gross customer trade receivables. We establish an allowance for estimated losses from the inability of our customers to pay as well as for specific receivables with known collection problems due to circumstances such as liquidity or bankruptcy. Collection problems are identified using an aging of receivables analysis based on invoice due dates. Items that are deemed uncollectible are written off against the allowance for collection losses. We do not require deposits or other collateral from our customers. If actual customer performance were to deteriorate to an extent not expected by us, additional allowances may be required. As of December 31, 2008 and 2007, our allowance for doubtful accounts was $786 and $762, respectively.

We maintain an allowance for credit memos based on our historical credit memo activity. In addition, we establish allowances for credit memos resulting from specific customer matters. This allowance is recorded as a direct reduction of accounts receivable and revenues. Since our allowances for credit memos are derived in large part from specific customer matters, our estimates have been consistent with our actual credit memo experience. If our billing errors or discrepancies are not resolved satisfactorily or our customers’ disputes over billing are not resolved satisfactorily, increases to the allowance would be required. As of December 31, 2008 and 2007, our allowance for credit memos was $1,561 and $2,557, respectively.

Property and Equipment, Net Property and equipment consist primarily of computer hardware and network equipment, leasehold improvements and furniture in our headquarter facilities, which are recorded at cost and depreciated using the straight-line method over the estimated remaining lives. Leasehold improvements are depreciated over the shorter of the term of the lease or life of asset.

The asset lives used are presented in the following table:

Average Lives (In Years) Computers and Equipment 5 Furniture and fixtures 6 Leasehold improvements 2 – 11

When the depreciable assets are replaced, retired or otherwise disposed of, the related cost and accumulated depreciation are deducted from the respective accounts and any gains or losses on disposition are recognized in income.

68 Table of Contents

Betterments, renewals and extraordinary repairs, which increase the value or extend the life of the asset, are capitalized. Repairs and maintenance costs are expensed as incurred.

Capitalized Software Costs We capitalize the cost of internal-use software, which has a useful life in excess of one year in accordance with Statement of Position (SOP) No. 98-1, Accounting for the Costs of Computer Software Developed or Obtained for Internal Use. Subsequent additions, modifications or upgrades to internal-use software are capitalized only to the extent that they allow the software to perform a task it previously did not perform. Software maintenance and training costs are expensed in the period in which they are incurred. Capitalized computer software costs are amortized using the straight-line method over a period of 3-12 years.

Goodwill Goodwill represents the excess of costs over fair value of assets of businesses acquired. Goodwill is not amortized, but is tested for impairment at the reporting-unit level, at least annually on October 1, or more frequently if indicators of impairment arise. A reporting unit is an operating segment or one level below an operating segment, referred to as a component. We have not identified any components within our single operating segment and, hence, have a single reporting unit for purposes of our goodwill impairment test.

Identifiable Intangible Assets Our identifiable intangible assets represent customer-related intangible assets, such as customer contracts and customer relationships associated with our acquisitions. We amortize identifiable intangible assets over their contractual or estimated useful lives of 5 to 20 years using the straight-line method. Estimated useful lives are determined primarily based on forecasted cash flows, which includes estimates for the revenues, expenses and customer attrition associated with the assets.

Impairment of Long-Lived Assets We evaluate for impairment our depreciable and amortizable long-lived assets including property and equipment, capitalized software and amortizable identifiable intangible assets. We utilize the three-step approach for recognizing and measuring the impairment of assets to be held and used. That is, (1) we consider whether indicators of impairment are present; (2) if indicators of impairment are present, we determine whether the sum of the estimated undiscounted future cash flows attributable to the long-lived asset in question is less than its carrying amount; and (3) if less, we recognize an impairment loss based on the excess of the carrying amount of the long-lived asset over its respective fair value. Fair value is estimated based on discounted future cash flows. Assets to be sold must be stated at the lower of the assets’ carrying amount or fair value and depreciation is no longer recognized. We believe the carrying values of our long-lived assets, including property and equipment and identifiable intangible assets, were not impaired as of December 31, 2008 and 2007.

Income Taxes We provide for federal, state and foreign income taxes currently payable, as well as for those deferred due to timing differences between reporting income and expenses for financial statement purposes versus tax purposes. Federal, state and foreign tax benefits are recorded as a reduction of income taxes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted income tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in income tax rates is recognized as income or expense in the period that includes the enactment date.

69 Table of Contents

We, and our eligible subsidiaries, file a consolidated U.S. federal income tax return. All subsidiaries incorporated outside of the U.S. are consolidated for financial reporting purposes, however, they are not eligible to be included in our consolidated U.S. federal income tax return. Separate provisions for income taxes have been recorded for these entities. We intend to reinvest substantially all of the unremitted earnings of our non-U.S. subsidiaries and postpone their remittance indefinitely. Accordingly, no provision for U.S. income taxes for these non-U.S. subsidiaries was recorded in the accompanying consolidated statements of income.

Interest in Joint Venture We hold a 5% interest in the joint venture mTLD Top Level Domain, Ltd., a joint venture formed to provide mobile data and content domain name registry services and development guidelines. We account for this investment using the cost method of accounting. As of December 31, 2008 and 2007, our investment was $888 and is included in other assets.

Fair Value of Financial Instruments Effective January 1, 2008, we adopted Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157), except as it applies to the nonfinancial assets and nonfinancial liabilities subject to FASB Staff Position (FSP) 157-2. SFAS 157 clarifies the definition of fair value, prescribes methods for measuring fair value, establishes a fair value hierarchy based on the inputs used to measure fair value, and expands disclosures about fair value measurements. See Note 14 for more information, including a listing of our assets and liabilities required to be measured at fair value on a recurring basis and where they are classified within the hierarchy as of December 31, 2008.

Derivative Instruments and Hedging Activities We account for derivative financial instruments under FASB Statement No. 133, Accounting for Derivative Instruments and Hedging Activities, as amended (FAS 133). Under FAS 133, all derivatives are recorded on the consolidated balance sheets as assets or liabilities and measured at fair value. For derivatives designated as cash flow hedges, the effective portion of the changes in fair value of the derivatives are recorded in accumulated other comprehensive income (loss) and subsequently recognized in earnings when the hedged items impact income. Changes in the fair value of derivatives not designated as hedges and the ineffective portion of cash flow hedges are recorded in current earnings. We have designated an interest rate swap as a cash flow hedge that effectively swaps variable rate interest expense based on 1-month LIBOR to a fixed rate interest expense thereby reducing our exposure to interest rate fluctuations. We do not hold or enter into financial instruments for speculative trading purposes. See Note 13 for more information on our interest rate swap.

Foreign Currencies We have significant operations in subsidiaries in Europe, including the United Kingdom, and the Asia-Pacific region whose functional currency is their local currency. Gains and losses on transactions denominated in currencies other than the functional currencies are included in determining net income for the period. For the years ended December 31, 2008, 2007, and 2006, we recorded transaction gain (loss) of $(401), $(40) and $1, respectively.

The assets and liabilities of subsidiaries whose functional currency is other than the U.S. Dollar are translated at the period-end rate of exchange. The resulting translation adjustment is recorded as a component of accumulated other comprehensive income (loss) and is included in stockholders’ equity. Translation gains and losses on intercompany balances which are deemed to be of a long-term investment nature are also recorded as a component of other comprehensive income. Income statement items are translated at the average rates prevailing during the period.

70 Table of Contents

Accumulated Other Comprehensive (Loss) Income Accumulated other comprehensive (loss) income is comprised of changes in our currency translation adjustment account, changes in our minimum pension liability account, net of tax and changes in the fair value of our interest rate swap, net of tax. Accumulated other comprehensive (loss) income for the three years ended December 31, 2008 is as follows:

Segment Information For all periods reported, we operated as a single segment, since our chief operating decision maker decides resource allocations on the basis of our consolidated financial results. Revenues by service offerings were as follows:

Year Ended December 31, 2008 2007 2006 Technology Interoperability Services $ 317,685 $ 184,471 $ 138,655 Network Services 122,529 124,788 124,832 Number Portability Services 29,291 27,128 28,766 Call Processing Services 29,720 31,421 29,315 Enterprise Solutions 2,387 4,084 7,289 Off-Network Database Queries 4,744 5,632 8,162 Total Revenues $ 506,356 $ 377,524 $ 337,019

Revenues by geographic region, based on the “bill to” location on the invoice, were as follows:

Year Ended December 31, 2008 2007 2006 North America (U.S. and Canada) $ 361,438 $ 291,186 $ 267,828 Asia Pacific 46,445 41,725 31,058 Caribbean and Latin America 30,666 23,860 20,204 Europe, Middle East and Africa 63,063 15,121 9,767 Off-Network Database Queries (i) 4,744 5,632 8,162 Total Revenues $ 506,356 $ 377,524 $ 337,019

(i) Off-Network Database Queries are not allocated to geographic regions.

For the year ended December 31, 2008, 2007 and 2006, we derived 67.9% and 73.3% and 77.4%, respectively, of our revenues from customers in the United States.

71 Table of Contents

Long-lived assets by geographic location were as follows:

Year Ended December 31, 2008 2007 United States $604,508 $ 612,014 Asia Pacific 42,870 42,639 Central and Latin America 32 — Europe, Middle East and Africa 268,205 300,145 Total $915,615 $ 954,798

Net Income Per Common Share We compute net income per common share in accordance with Statement of Financial Accounting Standards No. 128, Earnings Per Share (SFAS 128). Basic net income per common share includes no dilution and is computed by dividing earnings available to common shareholders by the weighted average number of common shares outstanding for the period. Earnings available to common shareholders are the same as reported net income for all periods presented. Diluted net income per common share includes the potential dilution from the exercise of stock options and restricted stock. For the years ended December 31, 2008, 2007 and 2006 options to purchase 603,076, 534,480 and 236,600 shares of common stock were outstanding during the periods but were not included in the computation of diluted earnings per share because their effect would be anti-dilutive. No additional securities were outstanding that could potentially dilute basic earnings per share that were not included in the computation of diluted earnings per share.

The following table displays the computation of net income per common share:

Year Ended December 31, 2008 2007 2006 Basic and diluted net income per common share: Net income available to common stockholders $ 78,464 $ 52,419 $ 89,724 Determination of basic and diluted shares: Basic weighted-average common shares outstanding 67,674,501 67,333,061 66,942,944 Unvested common stock — 47,515 295,363 Potentially dilutive stock options and restricted stock 422,765 150,891 60,039 Diluted weighted-average common shares outstanding 68,097,266 67,531,467 67,298,346 Basic net income per common share $ 1.16 $ 0.78 $ 1.34 Diluted net income per common share $ 1.15 $ 0.78 $ 1.33

Reclassifications Certain prior year balances have been reclassified to conform to the 2008 presentations.

3. Recent Accounting Pronouncements In September 2006, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157). SFAS 157 clarifies the principle that fair value should be based on the assumptions market participants would use when pricing an asset or liability and establishes a fair value hierarchy that prioritizes the information used to develop those assumptions. Under the standard, fair value measurements are separately disclosed by level within the fair value hierarchy. SFAS 157 is effective January 1, 2008. On February 12, 2008, the FASB issued FASB Staff Position (FSP) 157-2 which delays the effective date of SFAS No. 157 for one year, for all non financial assets and non financial liabilities, except those that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually). SFAS No. 157 and FSP 157-2 are effective for financial statements issued for fiscal years beginning after November 15, 2007. The partial adoption of SFAS 157 did not have a material impact on our financial position or results of operations.

72 Table of Contents

In February 2007, the FASB issued Statement of Financial Accounting Standards No. 159, The Fair Value Option for Financial Assets and Financial Liabilities—Including an Amendment of FASB Statement No. 115 (SFAS 159). This standard permits an entity to choose to measure many financial instruments and certain other items at fair value. The fair value option permits a company to choose to measure eligible items at fair value at specified election dates. A company will report unrealized gains and losses on items for which the fair value option has been elected in earnings after adoption. SFAS 159 was effective for us beginning on January 1, 2008. The adoption of SFAS 159 did not have a material impact on our financial position or results of operations and we did not elect to measure eligible items at fair value under this Statement.

In December 2007, the FASB issued Statement of Financial Accounting Standards No. 141 (revised 2007), Business Combinations (SFAS 141R). SFAS 141R provides revised guidance on how acquirers recognize and measure the consideration transferred, identifiable assets acquired, liabilities assumed, noncontrolling interests, and goodwill acquired in a business combination. SFAS 141R also expands required disclosures surrounding the nature and financial effects of business combinations. SFAS 141R is effective, on a prospective basis, for fiscal years beginning after December 15, 2008. The adoption of SFAS 141R will not have a material impact on our financial position and results of operations.

4. Acquisition of Interactive Technology Holdings Limited Business On June 16, 2006, we acquired the capital stock of Perfect Profits International (PPIL), which comprises the Interactive Technologies Holdings Limited business (ITHL), from Interactive Technologies Holdings Limited for $45,747 in cash including working capital adjustments and earn-out to the sellers of $6,894, which was paid in April 2007. Additionally, in connection with the acquisition, we incurred $1,106 in acquisition related costs. Headquartered in Hong Kong, ITHL is a leading provider of value-added services to operators in the Asia Pacific region. We believe the acquisition expands our footprint in the Asia Pacific region and adds a complementary customer base, new products, advanced development capabilities and in-region customer support. Since the acquisition was completed as of the close of business on June 16, 2006, ITHL’s operating results have only been included in our consolidated statement of income since that date.

The acquisition was accounted for using the purchase method of accounting. The total purchase price of $45,747 was allocated to the assets and liabilities based upon their fair value as of the date of the transaction. The fair value of the intangible assets (in-process research and development, completed technologies and customer relationship) and deferred revenues was determined by a third-party appraisal firm, using an income approach and estimates and assumptions provided by management. The following table summarizes the allocation of the purchase price based on the fair value of the net assets acquired and liabilities assumed.

Estimated Useful Amount Life Cash $ 1,131 Accounts receivable 7,180 Other current assets 7,240 Property and equipment 1,085 1 – 5 years In-process research and development 167 Completed technologies 6,514 6 years Customer relationships 4,298 7 years Goodwill 33,143 Total assets $ 60,758 Accounts payable 3,093 Other accrued liabilities 9,090 Deferred tax liabilities 2,828 Total liabilities $ 15,011 Total purchase price $ 45,747

The completed technologies and customer relationships were valued using discounted future cash flows. The valuations considered historical financial results and expected and historical trends. The future cash flows for the completed technologies and customer relationship were discounted using a weighted average cost of capital based upon an analysis of the cost of capital for guideline companies within the technology industry. The useful lives of the intangible assets were based on the period over which we expect these assets to contribute directly or indirectly to the future cash flows. The estimated useful lives of the completed technologies and customer relationships intangible assets are 6 and 7 years, respectively, and are being amortized over their estimated useful lives using the straight-line method.

In-process research and development (IPR&D) represents incomplete research and development projects that had not reached technological feasibility and had no alternative future use when acquired. Technological feasibility is established when an enterprise has completed all planning, design, coding and testing activities that are necessary to establish that a product can be produced to meet its design specifications including functions, features and technical performance requirements. The value of the IPR&D was determined using an income approach by considering estimated future revenues, cost to develop the acquisition-related IPR&D into commercially viable products and estimating the resulting net cash flows from the project when completed, which were discounted to their present value using a weighted average cost of capital of 25.0% due to the uncertainty of the future economic benefits. The acquired in- process research and development of $167 was written-off to general and administrative expense.

Deferred revenues (included in other accrued liabilities) are derived from maintenance contracts. The liability related to the deferred revenue was estimated by a third-party appraisal firm using a direct cost approach. The direct cost approach determines fair value by estimating the costs relating to fulfilling the obligation plus a normal profit margin. The estimated costs to fulfill the support obligations were based on the historical direct costs related to providing the support.

The fair values assigned to the remaining tangible assets and liabilities were internally developed. The purchase price over the fair values assigned to the net assets has resulted in the recognition of $33,143 in goodwill, which is subject to at least an annual impairment review. None of the goodwill is expected to be deductible for tax purposes.

5. Acquisition of BSG Wireless On December 19, 2007, we acquired the wireless data clearing and financial settlement business (BSG Wireless) of Billing Services Group Limited (BSG) pursuant to a Share Purchase Agreement, dated April 1, 2007. Under the Purchase Agreement, we acquired all of the outstanding share capital of Billing Services Group Luxembourg S. à r.l. and Billing Services Group Asia Limited from BSG for an aggregate purchase price of $294,402 in cash including acquisition related costs of $7,431. The acquisition was funded through the draw down of our amended and restated credit facility, which included a delayed draw term loan of $160,000 in aggregate principal amount and a Euro-denominated delayed draw term loan facility of the equivalent of $130,000 intended to finance this acquisition.

The acquisition was accounted for using the purchase method of accounting. The total purchase price of $294,402 was allocated to the assets and liabilities based upon their fair value as of the date of the transaction. The fair value of the intangible assets (customer relationship and capitalized software) and pension liabilities was determined by a third-party appraisal firm, using an income and replacement cost approach and estimates and assumptions provided by us. The following table summarizes the allocation of the purchase price based on the fair value of the net assets acquired and liabilities assumed at the acquisition date. We finalized our purchase price allocation in 2008, which resulted in a net decrease to goodwill of $3,603.

Estimated Useful Amount Life Cash $ 20,025 Accounts receivable 9,708 Other current assets 872 Property and equipment 1,133 1 – 5 years Capitalized software 14,018 5 years Customer relationships 61,300 9 years Goodwill 213,857 Total assets $ 320,913 Accounts payable 864 Other accrued liabilities 12,129 Other long-term liabilities 4,991 Deferred tax liabilities 8,527 Total liabilities $ 26,511 Total purchase price $ 294,402

The customer relationships were valued using discounted future cash flows. The valuation considered historical financial results and expected and historical trends. The future cash flows for the customer relationships were discounted using a weighted average cost of capital, which was based upon an analysis of the cost of capital for guideline companies within the technology industry. The capitalized software was valued using a replacement cost method based upon internally developed estimates. The useful lives of the intangible assets were based on the period over which we expect these assets to contribute directly or indirectly to the future cash flows. The estimated useful lives of the customer relationships and software intangible assets are 9 and 5 years, respectively, and are being amortized over their estimated useful lives using the straight-line method.

In connection with the BSG Wireless acquisition, we formulated a restructuring plan, which consists primarily of the elimination of redundant positions. As a result of this plan, we recorded $2,027 of employee termination benefits as liabilities in the purchase accounting in accordance with Emerging Issues Task Force Issue No. 95-3 (EITF 95-3), Recognition of Liabilities in Connection with a Purchase Business Combination. As of December 31, 2008, all of these amounts had been paid.

As part of the BSG Wireless acquisition, we assumed a noncontributory, unfunded defined benefit retirement plan for employees located in Germany. The benefits are based on employees’ annual compensation. The plan benefits are paid to employees at least 65 years of age that have been employed a minimum of ten years. As a result, we recorded pension liabilities of $4,466 in our purchase accounting, which are included in other long-term liabilities on the consolidated balance sheets.

BSG Wireless holds customer funds related to their financial settlement services due to the time taken to clear transactions with customers’ roaming partners. These funds are treated as a receivable and a corresponding payable until the funds are settled. As of December 31, 2007, the balance in these accounts was $7,774, which were netted in other accrued liabilities in our consolidated balance sheet.

The fair values assigned to the remaining tangible assets and liabilities were internally developed. The purchase price over the fair values assigned to the net assets has resulted in the recognition of $213,857 in goodwill, which is subject to at least an annual impairment review. We expect that the goodwill recorded will be deductible for tax purposes.

Since the acquisition was completed as of the close of business on December 19, 2007, the fair values have been included in our consolidated balance sheet as of December 31, 2007. However, none of BSG Wireless’ operating results for the period December 20, 2007 through December 31, 2007, which are not material, have been included in the consolidated statement of income. The unaudited pro forma results presented below include the effects of the BSG Wireless and ITHL acquisitions as if they had been consummated beginning on January 1, 2006. Pro forma adjustments arise primarily due to the asset revaluations. Because the selected pro forma consolidated financial information is based upon BSG Wireless’ and ITHL’s financial position and operating results during the period when BSG Wireless and ITHL were not under the control, influence or management of Syniverse, the selected pro forma financial information below is not necessarily indicative of either future results of operations or results that might have been achieved had the acquisitions been consummated on January 1, 2006:

Pro Forma for the Year Ended December 31, 2007 2006 Revenues $ 428,919 $ 394,002 Operating income 121,583 89,434 Net income 50,705 82,949 Net income per common share: Basic $ 0.75 $ 1.24 Diluted $ 0.75 $ 1.23

6. Stock-Based Compensation Syniverse has three stock-based compensation plans, the Founders’ Stock Option Plan for non-employee directors, executives and other key employees of Syniverse, the Directors’ Stock Option Plan, which provides for grants to independent directors, and the 2006 Long-Term Equity Incentive Plan, which provides incentive compensation through grants of incentive or non-qualified stock options, restricted stock, restricted stock units, stock appreciation rights (“SARs”), performance awards or any combination of the foregoing.

The impact to our income from operations of recording stock-based compensation for the years ended December 31, 2008, 2007 and 2006 was as follows:

Year Ended December 31, 2008 2007 2006 Cost of operations $ 169 $ 212 $ 153 Sales and marketing 1,233 650 378 General and administrative 3,803 2,702 1,289 Total stock-based compensation $5,205 $3,564 $1,820

During the year ended December 31, 2008, we issued 151,339 shares related to stock option exercises and 78,357 shares related to the employee stock purchase plan. During the year ended December 31, 2007, we issued 47,845 shares related to stock option exercises and 49,776 shares related to employee stock purchase plan issuances.

76 Table of Contents

Option Plans On May 16, 2002, our Board of Directors adopted a Founders’ Stock Option Plan for non-employee directors, executives and other key employees of Syniverse. In addition, the Board of Directors adopted a Directors’ Stock Option Plan on August 2, 2002, which provided for option grants to independent directors to purchase up to 20,000 shares upon election to the board. The plans had a term of five years and provided for the granting of options to purchase shares of Syniverse’s non-voting Class B common stock. As part of our initial public offering, we reclassified the Class B common stock into our common stock and hence all of our options now provide for purchase of our common stock.

Under the plans, the options have an initial exercise price based on the fair value of each share, as determined by the Board. The per share exercise price of each stock option will not be less than the fair market value of the stock on the date of the grant or, in the case of an equity holder owning more than 10% of the outstanding stock of Syniverse, the price for incentive stock options is not less than 110% of such fair market value. The Board of Syniverse reserved 402,400 shares of common stock, par value $.001 per share for issuance under the Founders’ plan and 160,360 shares under the Directors’ plan.

Both the Founder’s Stock Option Plan and the Directors’ Stock Option Plan have expired and the Board of Syniverse no longer grants options under these plans. As of December 31, 2008, there were options to purchase 135,234 shares outstanding under the Founder’s Stock Option Plan and options to purchase 100,240 shares outstanding under the Directors’ Stock Option Plan.

All options issued under the plans are presumed to be nonqualified stock options unless otherwise indicated in the option agreement. Each option has an exercisable life of no more than 10 years from the date of grant for both nonqualified and incentive stock options in the case of grants under the Founders’ Stock Option Plan and under the Directors’ Stock Option Plan. Generally, the options under these plans vest 20% after the first year and 5% per quarter thereafter.

2006 Long-Term Equity Incentive Plan On May 9, 2006, our Board of Directors adopted the 2006 Long-Term Equity Incentive Plan (the “Incentive Plan”). The Incentive Plan provides incentive compensation through grants of incentive or non-qualified stock options, restricted stock, restricted stock units, stock appreciation rights (“SARs”), performance awards, or any combination of the foregoing. The Incentive Plan is designed to allow for the grant of long term incentive awards that conform to the requirements for tax deductible “performance based” compensation under Section 162(m) of the Internal Revenue Code of 1986, as amended.

Under the Incentive Plan, 6,000,000 shares of common stock were authorized for issuance, of which 1,000,000 shares may be issued as restricted stock, restricted stock units, options, or performance shares. The number of shares and price per share is determined by the Compensation Committee (the “Committee”) for those awards granted. However, the exercise price of any option may not be less than 100% of the fair market value of a share of common stock on the date of grant and the exercise price of an incentive option awarded to a person who owns stock constituting more than 10% of Syniverse’s voting power may not be less than 110% of the fair market value on the date of grant. Those eligible to participate in the Incentive Plan are limited to directors (including non-employee directors), officers (including non-employee officers) and employees of Syniverse and its subsidiaries selected by the Committee, including participants located outside the United States. Determinations made by the Committee under the Incentive Plan need not be uniform and may be made selectively among eligible individuals under the Incentive Plan.

As of December 31, 2008, there were 1,550,403 options outstanding, ten year term and vesting 33 1/3% per year, which had been granted to certain directors, executive officers and other employees. As of December 31, 2008, there were 604,800 unvested restricted shares outstanding, vesting 20% per year, which had been granted to certain directors, executive officers and other employees.

Accounting for Stock-Based Compensation Stock Options The fair values of stock option grants are amortized as compensation expense on a straight-line basis over the vesting period of the grants. Compensation expense recognized is shown in the operating activities section of the consolidated statements of cash flows. The fair value for these options was estimated at the date of grant using a Black-Scholes option-pricing model with the following weighted-average assumptions:

Year Ended December 31, 2008 2007 2006 Risk-free interest rate 3.8% 4.7% 4.6% Volatility factor 34 34 34 Dividend yield — — — Weighted average expected life of options (in years) 5 5 5

The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options, which have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions including the expected stock price volatility. Prior to February 10, 2005, Syniverse’s common stock was not traded on public markets. Therefore, a volatility of 0% was used in the Black-Scholes option valuation model for options issued prior to our initial public offering. We use average historical volatility for options issued subsequent to our initial public offering.

SFAS 123(R) requires companies to estimate potential forfeitures of stock grants and adjust compensation cost recorded accordingly. Due to the minimal number of forfeitures we have experienced during the limited life of our option plans, as well as the minimal forfeitures we expect to experience, our forfeiture rate is not material to our fair value calculation; therefore, we estimate a zero percent forfeiture rate. We adjust the compensation expense for this estimate for actual forfeitures as they occur.

The following table summarizes information about our stock-based compensation activity:

Weighted- Weighted- Average Aggregate Average Remaining Intrinsic Exercise Contractual Value Stock Options Shares Price Term (000s) Outstanding at December 31, 2007 1,204,679 $ 13.72 8.35 $ 2,239 Granted 870,200 $ 15.98 Exercised (151,339) $ 13.13 Cancelled (137,663) $ 14.25 Outstanding at December 31, 2008 1,785,877 $ 14.84 8.35 $ —

During the years ended December 31, 2008, 2007 and 2006:

• the weighted average fair value per share of stock-based compensation granted to employees was $5.81, $5.06 and $6.11, respectively;

78 Table of Contents

• the total intrinsic value of stock options exercised was $964, $130 and $47, respectively; and

• the total fair value of stock options that vested during the periods was $1,590, $613 and $214, respectively.

The amount of cash received from the exercise of stock options was $1,987, $670 and $140 for the years ended December 31, 2008, 2007 and 2006, respectively. Tax benefits of $479, $0 and $0 were realized from the exercise of those options for the years end December 31, 2008, 2007 and 2006, respectively. Cash was not used to settle any equity instruments previously granted. There was no stock-based compensation cost capitalized into assets for the years ended December 31, 2008, 2007 and 2006, respectively.

A summary of our unvested shares activity is as follows:

Weighted- Average Grant-Date Fair Stock Options Shares Value Unvested at December 31, 2007 901,341 $ 4.99 Granted 870,200 $ 5.81 Vested (326,674) $ 4.87 Forfeited (134,958) $ 4.89 Unvested at December 31, 2008 1,309,909 $ 5.58

Restricted Stock Restricted stock awards are issued and measured at market value on the date of grant. Generally 20% vest per year from date of grant. Vesting of restricted stock is based solely on time vesting.

Changes in our restricted stock were as follows:

Weighted- Average Grant-Date Fair Restricted Stock Shares Value Unvested at December 31, 2007 796,000 $ 14.44 Granted 148,700 $ 17.15 Vested (173,400) $ 14.61 Forfeited (166,500) $ 14.47 Unvested at December 31, 2008 604,800 $ 15.06

As of December 31, 2008, there was $5,464 of total unrecognized compensation cost related to stock options and $7,390 related to restricted stock awards. The weighted average recognition period for the remaining unrecognized stock-based compensation cost is approximately two years.

Employee Stock Purchase Plan On May 9, 2006, our Board of Directors adopted the 2006 Employee Stock Purchase Plan (the “Purchase Plan”). All employees, including Directors who are employees and all employees of any subsidiary, are eligible to participate in any one or more of the offerings to purchase common stock under the Purchase Plan. Eligible employees may purchase a limited number of shares of Syniverse’s common stock at 85% of the market value during a series of offering periods. The purchase price is set based on the price on the New York Stock Exchange at the close of either the first or the last trading day of the offering period, whichever is lower. The fair value of shares issued under the Purchase Plan is estimated on the commencement date of each offering period using the Black-Scholes option pricing model.

79 Table of Contents

The following weighted-average assumptions were used in the model:

Year Ended December 31, 2008 2007 2006 Risk-free interest rate 3.3% 5.0% 5.1% Volatility factor 33 34 34 Dividend yield — — — Expected life (in months) 6 6 4

In 2006, the first offering was from August 1, 2006 through November 30, 2006. Beginning in 2007, each offering period is divided into semi-annual purchase intervals beginning June 1 and December 1 and has a maximum term of six months. The following table summarizes the Purchase Plan activity:

Year ended December 31, 2008 2007 2006 Shares Purchased 78,357 49,776 15,094 Average Price $ 10.19 $ 11.46 $ 11.19 Compensation expense $ 371 $ 159 $ 46

As of December 31, 2008, approximately 356,773 shares were reserved for future issuance. As of December 31, 2008, there were 126 enrollments under the Purchase Plan.

7. Concentration of Business Financial instruments that subject us to concentrations of credit risk are limited to our trade receivables from major customers and cash and cash equivalents. One customer represented more than 10% of accounts receivable for the year ended December 31, 2008. No customer represented more than 10% of accounts receivable for the year ended December 31, 2007. Our cash and cash equivalents are placed with high credit quality financial institutions and are invested in short-term maturity, highly-rate securities.

Sales to one customer were 15.0%, 14.9% and 17.6% of total revenues for the years ended December 31, 2008, 2007 and 2006, respectively. No other customer represented more than 10% of revenues for the years ended December 31, 2008, 2007 and 2006, although a significant amount of our remaining revenues were generated from services provided to a small number of other wireless operators.

11. Leasing Arrangements We lease certain facilities and equipment for use in our operations, all of which are operating leases. We record operating lease expenses on a straight- line basis over the term of the lease after taking into consideration rent holidays, rent escalations and leasehold incentives. Total rent expense under operating leases amounted to $8,710, $6,915 and $6,707 for the years ended December 31, 2008, 2007 and 2006, respectively. These contain various renewal options that could extend the terms of the leases beyond 2013 at our option.

As of December 31, 2008, the aggregate future minimum lease commitments under non-cancelable leases are as follows:

Year ended December 31, 2009 $ 7,540 Year ended December 31, 2010 6,186 Year ended December 31, 2011 5,182 Year ended December 31, 2012 4,914 Year ended December 31, 2013 4,738 Thereafter 13,657 $42,217

On February 28, 2005 we entered into an agreement to lease 199,000 square feet for our new corporate headquarters facility located in Tampa, Florida. The lease term is eleven years commencing on November 1, 2005 with lease payments beginning one year following the commencement date. The lease agreement for our former corporate headquarters expired October 31, 2006, however, we negotiated an early termination in accordance with the agreement. Under Statement of Financial Accounting Standards No. 146, Accounting for Costs Associated with Exit or Disposal Activities (SFAS 146), a liability for costs to terminate a contract before the end of its term should be recognized and measured at its fair value. For the year ended December 31, 2006, we recorded a lease termination loss of $1,280 which is included in general and administrative expenses, and a liability for lease termination costs for the same amount. As of December 31, 2006, all costs associated with the lease termination were paid and the liability was reduced to zero.

12. Debt and Credit Facilities The following are the amounts outstanding at December 31, 2008 and 2007:

Maturities of long-term debt for the years succeeding December 31, 2008 are as follows:

2009 $ 3,431 2010 3,431 2011 3,431 2012 3,431 2013 178,431 Thereafter 321,658 Total $ 513,813

We incurred debt issuance costs of $7,180 associated with our senior credit facility and $4,740 associated with our 7 3/4% Senior Subordinated Notes, which are included in deferred costs on the consolidated balance sheets. We amortize these costs over the term of the debt to interest expense using the effective interest method. Amortization expense for the years ended December 31, 2008, 2007 and 2006 for debt issuance costs was $1,742, $1,173 and $1,103, respectively.

Amended and Restated Senior Credit Facility On August 9, 2007, we entered into a $464,000 amended and restated credit agreement (the “senior credit facility”) with Lehman Brothers Inc. and Deutsche Bank Securities Inc. as joint lead arrangers and joint book-running managers, Lehman Commercial Paper Inc., as administrative agent, Deutsche Bank AG New York Branch, as syndication agent, Bear Stearns Corporate Lending Inc. and LaSalle Bank National Association, as co-documentation agents and the lenders from time to time parties thereto. The obligations under the senior credit facility are unconditionally guaranteed by Syniverse Holdings, Inc. and all material U.S. domestic subsidiaries of Syniverse Technologies, Inc. (the “Guarantors”) and are secured by a security interest in substantially all of the tangible and intangible assets of Syniverse Technologies, Inc. and the Guarantors. The obligations under the senior credit facility are also secured by a pledge of the capital stock of Syniverse Technologies, Inc. and its direct and indirect U.S. subsidiaries.

The senior credit facility provides for aggregate borrowings of $464,000 as follows:

• a term loan of $112,000 in aggregate principal amount;

• a delayed draw term loan of $160,000 in aggregate principal;

• a Euro-denominated delayed draw term loan facility of the equivalent of $130,000 at the draw date;

• a revolving credit line of $42,000; and

• a Euro-denominated revolving credit line of the equivalent of $20,000.

As of December 31, 2008 and 2007, we had $338,813 ($213,162 in U.S. dollar denominated term loans and $125,651 in Euro-denominated term loans) and $347,935 ($215,320 in U.S. dollar denominated term loans and $132,615 in Euro-denominated term loans), respectively, of outstanding indebtedness under the term loans. As of December 31, 2008, the applicable interest rate was 2.97% on the term loan and revolving credit line based on the LIBOR option and 5.20% on the Euro-denominated term loan and Euro-denominated credit line based on the EURIBOR option. As of December 31, 2008 and 2007, the balance of our revolving credit line and Euro-denominated credit line was $0.

The credit agreement allows us to request letters of credit up to an aggregate of $15,000. We are required to pay a fee equal to the applicable margin then in effect in respect to revolving loans and a fee to the issuing lender of 1/8 of 1% per annum in addition to normal and customary fees paid to the issuer of the letter of credit. On December 31, 2008, we had an Euro letter of credit outstanding of the equivalent of $1,974.

On December 19, 2007, the delayed draw term loans of $290,000 were used to fund the acquisition of BSG Wireless described in Note 5 above, including the repayment of existing debt of Billing Services Group and to pay related transaction fees and expenses. The delayed draw term loans were subject to a commitment fee of 1.25% per annum on undrawn amounts. The commitment to fund the delayed draw term loans expired at the earliest to occur of (i) the draw down to fund the acquisition of BSG, (ii) termination of the BSG acquisition agreement or (iii) March 31, 2008.

U.S. dollar denominated borrowings under the senior credit facility bear interest at variable rates, at Syniverse’s option, of either:

• a base rate generally defined as the sum of (i) the higher of (x) the prime rate (as quoted on Page 5 of the British Banking Association Telerate

screen) and (y) the federal funds effective rate, plus one half percent (0.50%) per annum and (ii) an applicable margin or,

• a LIBOR rate generally defined as the sum of (i) the rate at which Eurodollar deposits for one, two, three, six or nine months and, if available to the lenders under the applicable credit facility, twelve months (as selected by us) are offered in the interbank Eurodollar market and (ii) an applicable margin.

Euro-denominated borrowings under the senior credit facility bear interest at variable rates, at Syniverse’s option, of either:

• a base rate generally defined as the sum of (i) the higher of (x) the prime rate (as quoted on Page 5 of the British Banking Association Telerate

screen) and (y) the federal funds effective rate, plus one half percent (0.50%) per annum and (ii) an applicable margin or,

• a EURIBOR rate generally defined as the sum of (i) the rate at which Euro deposits for one, two, three, six or nine months and, if available to the lenders under the applicable credit facility, twelve months (as selected by us) are offered in the interbank Euro market and (ii) an applicable margin. The applicable margin for the base rate term loan and base rate revolving loans is 1.50% and the applicable margin for the Eurodollar term loan, Euro- denominated term loan and Eurodollar revolving loans is 2.50%. The term loan facilities require regularly scheduled quarterly payments of principal and the entire amount of the term loan facilities will mature on August 9, 2014. The timing of interest payments is determined by the rate selected. The full amount borrowed under the revolving credit line will mature on August 9, 2013. In the event we fail to refinance our 7 3/4% senior subordinated notes by February 15, 2013, then the maturity date of our term loan facilities and revolving credit line will be accelerated to February 15, 2013.

We are required to pay a commitment fee on the difference between committed amounts and amounts actually utilized under the revolving credit facility at a rate of 0.50% per annum for any quarter where our consolidated leverage ratio is greater than 3.0 to 1, 0.375% per annum for any quarter which our consolidated leverage ratio is greater than 2.0 to 1, but less than or equal to 3.0 to 1 and 0.25% for any fiscal quarter in which our consolidated leverage ratio is equal to or less than 2.0 to 1.

Under the terms of the senior credit facility at least 25% of our funded debt must bear interest that is effectively fixed. To that extent, we may be required to enter into interest rate protection agreements establishing a fixed maximum interest rate with respect to a portion of our total indebtedness. In October 2008, we entered into an interest rate swap that effectively fixes our funded debt at 53.5%.

The senior credit facility contains covenants that will limit our ability and that of our Guarantors to, among other things, incur or guarantee additional indebtedness, create liens, pay dividends on or repurchase stock, make certain types of investments, restrict dividends or other payments from our subsidiaries, enter into transactions with affiliates and sell assets or merge with other companies. The senior credit facility also requires compliance with financial covenants, including a maximum ratio of total indebtedness to Consolidated EBITDA.

Our obligations under the senior credit facility and the guarantees are secured by:

• a perfected first priority security interest in all of our tangible and intangible assets and all of the tangible and intangible assets of Syniverse. and

each of its direct and indirect subsidiaries, subject to certain customary exceptions, and

• a pledge of (i) all of the capital stock of the direct and indirect domestic subsidiaries and (ii) two-thirds of the capital stock of certain first-tier

foreign subsidiaries, if any.

On October 5, 2008, Lehman Commercial Paper Inc. (Lehman CPI) filed a petition under Chapter 11 of the U.S. Bankruptcy Code with the U.S. Bankruptcy Court for the Southern District of New York. Lehman CPI is the administrative agent of our senior credit facility. Lehman CPI has $28,200 (45.5 percent) of the $62,000 in commitments under our undrawn revolving credit line. It is doubtful Lehman CPI will honor its obligations under the revolving credit line. We do not expect that the Lehman CPI bankruptcy filing will have a material adverse effect on our liquidity or financial position.

7 3/4% Senior Subordinated Notes Due 2013

On August 24, 2005, we completed a private offering of $175,000 of its 7 3/4% Senior Subordinated Notes due 2013. Interest on the notes will accrue at the rate of 7 3/4% per annum and will be payable semi-annually in arrears on February 15 and August 15, commencing on February 15, 2006. The net proceeds were used to tender $144,750 of our outstanding 12 3/4 % senior subordinated notes due 2009. On February 1, 2006, the remaining funds were used to redeem the remaining 12 3/4% senior subordinated notes due 2009 not tendered in August 2005 of $14,500, plus payment of related premium of approximately $924. The balance of funds necessary for the redemption was paid from cash on hand.

The 7 3/4% Senior Subordinated Notes due 2013 are general unsecured obligations of Syniverse Technologies, Inc., and are unconditionally guaranteed by Syniverse Holdings, Inc. and each of the domestic subsidiaries of Syniverse Holdings, Inc. At any time prior to August 15, 2008, we may on any one or more occasions redeem up to 35% of the aggregate principal amount of notes issued under the indenture (including additional notes, if any) at a redemption price of 107.75% of the principal amount, plus accrued and unpaid interest and liquidated damages, if any, to the redemption date, with the net cash proceeds of one or more qualifying equity offerings by us or a contribution to our common equity capital made with the net cash proceeds of a concurrent equity offering by us (but excluding any reserved contribution); provided that:

(1) at least 65% of the aggregate principal amount of notes issued under the indenture (including additional notes, if any) remains outstanding

immediately after the occurrence of such redemption; and

(2) the redemption occurs within 90 days of the date of the closing of such equity offering.

The notes may be redeemed, in whole or in part, at any time prior to August 15, 2009, at our option upon not less than 30 nor more than 60 days’ notice, at a redemption price equal to 100% of the principal amount of the notes redeemed plus the applicable premium as of, and accrued and unpaid interest and liquidated damages, if any, to, the applicable redemption date, subject to the rights of note holders on the relevant record date to receive interest on the relevant interest payment date.

Except pursuant to the two preceding paragraphs, the notes will not be redeemable at our option prior to August 15, 2009. We are not prohibited, however, from acquiring the notes by means other than a redemption, whether pursuant to a tender offer or otherwise, assuming such acquisition does not otherwise violate the terms of the indenture.

After August 15, 2009, we may redeem all or a part of the notes upon not less than 30 nor more than 60 days’ notice, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest and liquidated damages, if any, on the notes redeemed, to the applicable redemption date, if redeemed during the twelve-month period beginning on August 15 of the years indicated below, subject to the rights of note holders on the relevant record date to receive interest on the relevant interest payment date:

Unless we default in the payment of the redemption price, interest will cease to accrue on the notes or portions thereof called for redemption on the applicable redemption date. we are not required to make mandatory redemption or sinking fund payments with respect to the notes.

The notes contain various other provisions in the event of a change in control or asset sales, and they also contain certain covenants that will, among other things, limit our ability to incur additional indebtedness and issue preferred stock, pay dividends, make other restricted payments and investments, create liens, incur restrictions on the ability of their subsidiaries to pay dividends or other payments to them, sell assets, merge or consolidate with other entities, and enter into transactions with affiliates.

On December 8, 2005, we completed an exchange of its 7 3/4% Series B Senior Subordinated Notes due 2013, which have been registered under the Securities Act of 1933, as amended, for any and all outstanding 7 3/4% Senior Subordinated Notes due 2013. All of the $175,000 in aggregate principal amount of the 7 3/4% Senior Subordinated Notes due 2013 were validly tendered for exchange and have been accepted by Syniverse. The new notes have substantially identical terms of the 7 3/4% Senior Subordinated Notes due 2013, except the new notes have been registered under the Securities Act of 1933, as amended.

12 3/4% Senior Subordinated Notes due 2009

On February 1, 2006, we completed an early redemption for all remaining notes of $14,500 in aggregate principal amount of its outstanding 12 3/4% Senior Subordinated Notes due 2009 at a premium of $924.

13. Derivative Instruments and Hedging Activities In March 2008, the FASB issued Statement of Financial Accounting Standards No. 161, Disclosures about Derivative Instruments and Hedging Activities-an amendment of FASB Statement No. 133 (SFAS 161). SFAS 161 requires enhanced disclosures about an entity’s derivative and hedging activities, and is effective for financial statements issued for reporting periods beginning after November 15, 2008, with early application encouraged. We elected to early-adopt the disclosure requirements set forth in SFAS 161 as of December 31, 2008.

On October 6, 2008, we entered into an interest rate swap agreement to hedge $100,000 of our U.S.-denominated term loan under our senior credit facility to manage interest rate risk. The hedge effectively swaps variable rate interest expense based on 1-month LIBOR to a fixed rate interest expense thereby reducing our exposure to interest rate fluctuations for the next two years. This agreement involves the receipt of floating rate amounts in exchange for fixed rate interest payments over the life of the agreement without an exchange of the underlying principal amount. The effective date of the swap is October 31, 2008 and the maturity date is October 31, 2010. The fixed rate is 5.26% based on our 2.76% swap rate plus our 2.50% applicable margin.

We have designated the interest rate swap as a cash flow hedge in accordance with SFAS 133. The counterparty to this interest rate swap agreement is a major financial institution, and we do not anticipate nonperformance by this counterparty. Changes in the fair value of the interest rate swap that are effective are recorded in accumulated other comprehensive income (loss) within the accompanying consolidated statement of stockholders’ equity. There was no ineffective portion of the swap during the year ended December 31, 2008. As of December 31, 2008, the fair value of our interest rate swap (based on Level 2 inputs) is $2,925, which is recorded in other long-term liabilities in the consolidated balance sheets. As of December 31, 2008, we recognized other comprehensive loss of $1,832, net of tax, related to the effectively hedged portion of the swap.

86 Table of Contents

Over the next twelve months, we expect to reclassify $1,825 of losses on our interest rate swap from accumulated other comprehensive income to earnings due to the payment of variable interest associated with the floating rate debt.

Net Investment Hedge of a Foreign Operation We have designated our Euro-denominated debt described in Note 12 as a net investment hedge of certain foreign operations. For the years ended December 31, 2008, 2007 and 2006, $5,655, $(2,932) and $0, respectively, related to the revaluation of the debt from Euros to US dollars was included as a component of accumulated other comprehensive income (loss).

14. Fair Value of Financial Instruments SFAS 157 requires disclosure about how fair value is determined for assets and liabilities and establishes a hierarchy for which these assets and liabilities must be grouped, based on significant levels of inputs. The three-tier fair value hierarchy, which prioritizes the inputs used in the valuation methodologies is as follows: Level 1—Quoted prices for identical assets and liabilities in active markets. Level 2—Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3—Unobservable inputs for the asset or liability.

As of December 31, 2008, we held certain items that are required to be measured at fair value on a recurring basis including an interest rate swap agreement. Cash and cash equivalents, accounts receivable, accounts payable and accrued expenses are reflected in the financial statements at their carrying value, which approximate their fair value due to their short maturity.

The following item is measured at fair value on a recurring basis subject to the disclosure requirements of SFAS 157 as of December 31, 2008:

Fair Value Measurements at Reporting Date Using Quoted Prices in Active Markets Significant for Identical Significant Other Unobservable December 31, Assets Observable Inputs Inputs 2008 (Level 1) (Level 2) (Level 3) Liabilities Interest rate swap $ (2,925) $ — $ (2,925) $ —

We have elected to use the income approach to value our interest rate swap, using observable Level 2 market expectations at measurement date and standard valuation techniques to convert future amounts to a single present value amount assuming that participants are motivated, but not compelled to transact.

The fair value of the 7 3/4% Senior Subordinated Notes due 2013 is based upon quoted market prices in inactive markets for similar instruments (Level 2 as defined under SFAS No. 157). The fair value of the Term Note B is based upon quoted market prices in active markets for similar instruments (Level 2 as defined under SFAS No. 157).

The carrying amounts and fair values of our long-term debt as of December 31, 2008 and 2007 are as follows:

2008 2007 Carrying Fair Carrying Fair Value Value Value Value Term Note B $ 338,813 $ 304,932 $ 347,935 $ 341,514 7 3/4% Senior Subordinated Notes, due 2013 175,000 $ 89,250 175,000 168,219

15. Commitments and Contingencies We are currently a party to various claims and legal actions that arise in the ordinary course of business. We believe such claims and legal actions, individually and in the aggregate, will not have a material adverse effect on our business, financial condition or results of operations. As of December 31, 2008, we have considered all of the claims and disputes of which we are aware and have provided for probable losses.

16. Restructurings In connection with the IOS North America acquisition on September 30, 2004, we began to formulate restructuring plans, which consisted primarily of the relocation of key IOS North America employees and the elimination of redundant positions. As a result of these plans, we recognized $1,888 of employee relocation costs and termination benefits as liabilities in the purchase accounting in accordance with EITF 95-3. We paid the remainder of these benefits in 2006.

In February 2006, we completed a restructuring plan in our marketing group resulting in the termination of 8 employees. As a result, we incurred $338 in severance related costs and made payments for the same amount in 2006. In August 2006, we completed a restructuring plan in our operations and marketing groups, resulting in the termination of 30 employees. As a result, we incurred $741 in severance related costs and made payments of $710 through the fourth quarter of 2007. The balance in this restructuring accrual was reduced to zero during the first quarter of 2008.

For the year ended December 31, 2006, we had the following activity in our restructuring accruals:

December 31, 2005 December 31, 2006 Balance Additions Payments Reductions Balance September 2004 Restructuring* Termination costs $ 394 $ — $ (330) $ (64) $ — Relocation costs 98 — (89) (9) — February 2006 Restructuring Termination costs — 338 (338) — — August 2006 Restructuring Termination costs 668 (512) — 156 Total $ 492 $ 1,006 $(1,269) $ (73) $ 156

In January 2007, we completed a restructuring plan resulting in the closure of our Oklahoma office, the elimination of certain executive positions, and the termination of 10 employees. As a result, we incurred $664 in severance related costs and $1,384 in costs associated with the lease termination of our corporate aircraft described below. In June 2007, we committed to a restructuring plan affecting our technology development and support groups. We estimated that the plan would result in the elimination of 56 employees over the remainder of the year. As a result, we accrued $572 in severance related costs. During the third and fourth quarter of 2007, we experienced a higher than expected level of attrition among the employees impacted by the offshoring plan resulting in a reduction of our severance liability of $449. The balance in this restructuring accrual was reduced to zero during the third quarter of 2008.

Effective March 1, 2002, we entered into an operating lease for the use of an executive aircraft. The lease was for seven years, ending March 1, 2009, and required monthly payments plus actual expenses for maintenance, fuel and other usage related charges. We had an option to purchase the aircraft 36 months after the commencement date of the lease at a price of $6,650 but did not exercise this option. Our former CEO and one of his affiliated entities were entitled to use the aircraft and were required to pay for the actual use of the aircraft

88 Table of Contents related to the affiliated entity. In January 2007, we ceased use of our corporate aircraft and terminated the lease in June 2007. This early termination resulted in the recording of $1,384 in restructuring costs. As of December 31, 2007, no amounts were owed by our former CEO.

For the year ended December 31, 2007, we had the following activity in our restructuring accruals:

December 31, 2006 December 31, 2007 Balance Additions Payments Reductions Balance August 2006 Restructuring Termination costs $ 156 $ 73 $ (198) $ (11) $ 20 January 2007 Restructuring Termination costs — 664 (457) (22) 185 Contract termination costs — 1,384 (1,384) — — June 2007 Restructuring Termination costs — 572 — (449) 123 December 2007 Restructuring* Termination costs — 2,027 — — 2,027 Total $ 156 $ 4,720 $(2,039) $ (482) $ 2,355

In connection with the BSG Wireless acquisition in December 2007, we formulated a restructuring plan, which consisted primarily of the elimination of redundant positions. As a result of this plan, we estimated $2,027 of employee termination benefits as liabilities in our purchase accounting in accordance with Emerging Issues Task Force Issue No. 95-3 (EITF 95-3), Recognition of Liabilities in Connection with a Purchase Business Combination. The balance in this restructuring accrual was reduced to zero during the fourth quarter of 2008.

For the year ended December 31, 2008, we had the following activity in our restructuring accruals:

17. Employee Benefits Savings Plans of Syniverse In 2002, we adopted a 401(k) plan covering all employees subject to certain eligibility requirements. Under this plan, a certain percentage of eligible employee contributions are matched. Contributions made to the 401(k) plan were $2,558, $2,263 and $2,359 for the years ended December 31, 2008, 2007 and 2006, respectively.

Pension Plan As part of the BSG Wireless acquisition described in Note 5, we assumed a noncontributory, unfunded defined benefit retirement plan for employees located in Germany. The benefits are based on employees’ annual

89 Table of Contents compensation. The plan benefits are paid to employees at least 65 years of age that have been employed a minimum of ten years. We recorded pension liabilities of $4,335 and $4,446 as of December 31, 2008 and 2007, respectively, which are included in other long-term liabilities on the consolidated balance sheet.

Assumptions used in determining the benefit obligations for pension and other postretirement plans as of December 31, 2008, were as follows:

Discount rate 6.0% Average compensation increase (salaried employees only) 3.0%

The following table provides a reconciliation of benefit obligation, plan assets, and funded status of the plan as of December 31, 2008 and 2007:

December 31, 2008 2007 Projected benefit obligation $4,335 $ 4,466 Plan assets at fair value — — Net liability in other long-term liabilities $4,335 $ 4,466

The following table provides a reconciliation of the change in the benefit obligation for year ended December 31, 2008 and 2007:

December 31, 2008 2007 Benefit obligation at beginning of year $4,466 $ — Service cost 222 — Interest cost 235 — Actuarial (gain) or loss (392) — Benefits paid (4) — Acquisition of BSG Wireless — 4,466 Effect of currency translation (192) — Balance at end of year $4,335 $4,466

Net benefit cost for the year ended December 31, 2008, included the following components:

Service cost on benefits earned during the year $222 Interest cost on projected benefit obligation 235 Net benefit expense $457

We estimate benefit payments for each of the next five years and in aggregate for the five years thereafter as follows:

Fiscal year: 2009 $ 8 2010 16 2011 21 2012 32 2013 53 2014 – 2018 828

18. Stockholder Rights Plan On November 16, 2008, our Board of Directors adopted a stockholder rights plan which declared a dividend of one preferred share purchase right (the “Right”) for each outstanding share of Common Stock, par value $0.001 per share (the “Common Shares”), of the Company. The dividend was payable on November 28, 2008 to the stockholders of record on that date. Each Right entitles the registered holder to purchase from the Company one one-thousandth of a share (a “Unit”) of Series A Junior Participating Preferred Stock, par value $0.01 per share (the “Preferred Shares”), at a price of $33 per one one-thousandth of a Preferred Share (the “Purchase Price”), subject to adjustment. Each Unit has designations and powers, preferences and rights, and the qualifications, limitations and restrictions designed to make it the economic equivalent of a Common Share. The description and terms of the Rights are set forth in the Rights Agreement dated November 16, 2008. As of December 31, 2008, there were 64,456 Preferred Shares issuable under the plan.

The Rights will separate from the common stock and will become exercisable only when a public announcement or notice to the company has been made that a person or group has acquired, or obtained the right to acquire beneficial ownership of 15% or more of the outstanding shares of the Company’s common stock (an “Acquiring Person”), other than as a result of an offer approved by the Board of Directors of the Company and (ii) 10 business days (or, if determined by the Board of Directors, a specified or unspecified later date) following the commencement or announcement of an intention to make a tender offer or exchange offer which, if successful, would cause the bidder to own 15% of more of the outstanding Common Shares (the earlier of such dates being called the “Distribution Date”). Until a Right is exercised, the holder thereof, as such, will have no rights as a stockholder of the Company, other than rights resulting from such holder’s ownership of Common Shares, including, without limitation, the right to vote or to receive dividends.

19. Income Taxes The components of income tax expense (benefit) are as follows:

Year Ended December 31, 2008 2007 2006 Current: Federal $18,152 $ 3,734 159 Foreign 2,072 920 571 State and local 822 529 — 21,046 5,183 730 Deferred Federal 19,993 23,317 (35,987) Foreign 3,140 132 (291) State and local 2,618 2,678 (4,026) 25,751 26,127 (40,304) Provision for (benefit from) income taxes $46,797 $31,310 (39,574)

We recognized a deferred tax benefit throughout 2006 from the utilization of our valuation allowance and, in 2006, we released $49,179 of the remaining valuation allowance recorded against the federal net operating loss carryforwards (“NOL’s). We have determined that it is more likely than not that we will realize the benefit of our net deferred tax assets for which we have not established a valuation allowance.

91 Table of Contents

The income tax expense differs from amounts computed by applying the U.S. statutory rate of 35% to pre-tax income from operations as follows:

Year Ended December 31, 2008 2007 2006 Statutory federal income tax rate 35.0% 35.0% 35.0% State and local income tax, net of federal tax benefit 3.4 3.8 3.7 Impact of foreign tax rates (0.9) (0.6) (0.1) Expired losses 0.0 0.0 21.2 Other, net (0.4) .8 (1.3) Change in valuation allowance 0.3 (1.6) (137.4) 37.4% 37.4% (78.9)%

On January 1, 2007 we adopted FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes (“FIN 48”), resulting in a change to our reserve for uncertain tax positions which was accounted for as a $2,791 cumulative affect adjustment to decrease the beginning balance of retained earnings on our balance sheet. No further activity occurred in this account during the remainder of 2007. As of December 31, 2008, we had $9,079 of total gross unrecognized tax benefits. The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate, was $6,770 at December 31, 2008. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

Year Ended December 31, 2008 2007 Balance at January 1 $ 9,016 $ 9,016 Additions based on tax positions related to the current year 2 0 Additions for tax positions of prior years 61 0 Reductions for tax positions of prior years 0 0 Settlements 0 0 Balance at December 31 $ 9,079 $ 9,016

We recognize accrued interest and penalties related to uncertain tax positions as a component of income tax expense. Accrued interest and penalties were $14 during 2008.

Tax years 2005 through 2008 and 2004 through 2008 are subject to examination by the federal and state taxing authorities, respectively. There are no income tax examinations currently in process. In our international tax jurisdictions, numerous tax years remain subject to examination by tax authorities, including tax returns for at least 2003 and subsequent years in all of our major international tax jurisdictions.

We intend to directly re-invest income from all of our foreign subsidiaries. The aggregate undistributed earnings of our foreign subsidiaries for which no deferred tax liability has been recorded is approximately $17,131 at December 31, 2008. Determination of the amount of unrecognized deferred tax liability on these undistributed earnings is not practicable.

The components of pretax income from operations are as follows:

Year Ended December 31, 2008 2007 2006 United States $108,259 $81,052 $ 46,649 Foreign 17,002 2,677 3,501 $125,261 $83,729 $ 50,150

Deferred income tax assets and liabilities are recorded due primarily to different carrying amounts for financial and income tax reporting purposes arising from cumulative temporary differences. Significant components of deferred tax (liabilities) assets are shown in the following table:

The activity in deferred tax assets during 2008 includes the deferred tax impact of the loss on the interest rate swap and a foreign currency translation adjustment totaling $945 to increase the deferred tax asset on accumulated other comprehensive income (loss). These items did not impact deferred income tax expense for 2008.

Our deferred tax assets arise primarily from accumulated foreign NOL’s of $25,848 and accumulated state NOL’s of $100,981. The foreign NOL’s remain available indefinitely to offset future taxable income in specific jurisdictions subject to applicable tax laws and regulations while state NOL’s in specific jurisdictions will expire if not utilized between tax years 2008 and 2024. We continue to maintain a valuation allowance for deferred tax assets primarily associated with certain foreign and state NOL’s and capital loss carryforwards.

The net change in the deferred income tax valuation allowance was a decrease of $1,993 in 2008 and an increase of $1,381 in 2007.

Amendment No. 1 to the Employment Agreement with Michael J. O’Brien

This Amendment No. 1 to the Employment Agreement dated as of January 9, 2006 (the “Agreement”), between Syniverse Technologies, Inc. (the “Company”), Syniverse Holdings, Inc. and Michael J. O’Brien (“Executive”) is made this 22 day of December 2008.

The Company and Executive have determined that it is in their best interests to amend the Agreement to include special provisions intended to ensure documentary compliance with Internal Revenue Code Section 409A relating to deferred compensation. In consideration of the mutual covenants contained herein and the continued employment of Executive by the Company, the parties agree as follows: 1. Section 409A. The Agreement is hereby amended by adding the following Section 25: “25. Provisions Relating to Section 409A of the Code (a) General. This Agreement shall be interpreted and administered in a manner so that any amount or benefit payable hereunder shall be paid or provided in a manner that is either exempt from or compliant with the requirements Section 409A of the Internal Revenue Code of 1986, as amended, and applicable Internal Revenue Service guidance and Treasury Regulations issued thereunder (and any applicable transition relief under Section 409A of the Code) (“Section 409A”). Nevertheless, the tax treatment of the amounts or benefits provided under the Agreement is not warranted or guaranteed. Neither the Company nor its directors, officers, employees or advisers shall be held liable for any taxes, interest, penalties or other monetary amounts owed by Executive as a result of the application of Section 409A. (b) Separation from Service. Notwithstanding anything in this Agreement to the contrary, as required by Section 409A, to the extent that any amount or benefit that would constitute non-exempt “deferred compensation” for purposes of Section 409A of the Code would otherwise be payable or distributable hereunder by reason of the Executive’s termination of employment, such amount or benefit will not be payable or distributable to Executive unless the circumstances giving rise to such termination of employment meet any description or definition of “separation from service” in Section 409A (without giving effect to any elective provisions that may be available under such definition). This provision does not prohibit the vesting of any amount upon Executive’s termination of employment or the determination of the amounts owed to him due to such termination. If this provision prevents the payment or distribution of any amount or benefit, such payment or distribution shall be made on the date, if any, on which an event occurs that constitutes a Section 409A-compliant “separation from service,” or such later date as may be required by subsection (c) below. (c) Six-Month Delay in Certain Circumstances. Notwithstanding anything in this Agreement to the contrary, as required by Section 409A, if any amount or benefit that would constitute non-exempt “deferred compensation” for purposes of Section 409A of the Code would otherwise be payable or distributable under this Agreement by reason of Executive’s separation from service during a period in which he is a Specified Employee (as defined below), then, subject to any permissible acceleration of payment by the Company under Treas. Reg. Section 1.409A-3(j)(4)(ii) (domestic relations order), (j)(4)(iii) (conflicts of interest), or (j)(4)(vi) (payment of employment taxes), the amount of such non-exempt deferred compensation that would otherwise be payable during the six-month period immediately following Executive’s separation from service will be accumulated and Executive’s right to receive payment or distribution of such accumulated amount will be delayed until the earlier of (i) a date no later than thirty (30) days following Executive’s death or (ii) the first day of the seventh month following Executive’s separation from service, whereupon the accumulated amount will be paid or distributed to Executive on such date and the normal payment or distribution schedule for any remaining payments or distributions will resume. For purposes of this Agreement, the term “Specified Employee” has the meaning given such term in Section 409A: provided, however, that the Company’s Specified Employees and its application of the six-month delay rule of Code Section 409A(a)(2)(B)(i) shall be determined in accordance with rules adopted by the Board or a committee thereof, which shall be applied consistently with respect to all nonqualified deferred compensation arrangements of the Company, including this Agreement. (d) Timing of Waiver and Release of Claims. Whenever in this Agreement the provision of payment or benefit is conditioned on Executive’s execution and non-revocation of a waiver and release of claims, such waiver and release must be executed, and all revocation periods must have expired, within 60 days after the date of termination of Executive’s employment, but the Company may elect to commence payment at any time during such 60- day period. (e) Timing of Reimbursements and In-kind Benefits. If Executive is entitled to be paid or reimbursed for any taxable expenses under this Agreement, including but not limited to subsection 3(f) and Section 23, and such payments or reimbursements are includible in Executive’s federal gross taxable income, the amount of such expenses reimbursable in any one calendar year shall not affect the amount reimbursable in any other calendar year, and the reimbursement of an eligible expense must be made no later than December 31 of the year after the year in which the expense was incurred. No right of Executive to reimbursement of such expenses shall be subject to liquidation or exchange for another benefit. Any reimbursement shall be for expenses incurred during Executive’s lifetime (or during a shorter period of time specified in this Agreement).

- 2 - (f) Treatment of Installment Payments. Each payment of termination benefits under Section 6(c) of this Agreement shall be considered a separate payment, as described in Treas. Reg. Section 1.409A-2(b)(2), for purposes of Section 409A.”

2. Except as expressly amended hereby, the terms of the Agreement shall be and remain unchanged and the Agreement as amended hereby shall remain in full force and effect.

IN WITNESS WHEREOF, the Company and Executive have caused this Amendment to be duly executed.

Garcia, Employer, and the Company agree that the Release shall be construed as broadly and generally as the law permits.

(b) Garcia agrees that he is waiving all rights to sue or obtain equitable, remedial or punitive relief from all or any Released Entities of any kind whatsoever, including, without limitation, reinstatement, back pay, front pay, attorneys’ fees and any form of injunctive relief. Notwithstanding the above, Garcia further acknowledges that he is not waiving and is not being required to waive any right that cannot be waived under law, including the right to file an administrative charge or participate in an administrative investigation or proceeding; provided, however, that Garcia disclaims and waives any right to share or participate in any monetary award resulting from the prosecution of such charge or investigation or proceeding.

(c) In signing this Agreement, Garcia acknowledges that he intends that this Release shall be effective as a bar to each and every one of the Claims hereinabove mentioned or implied. Garcia expressly consents that this Release shall be given full force and effect according to each and all of its express terms and provisions, including those relating to unknown and unsuspected Claims (notwithstanding any state statute that expressly limits the effectiveness of a general release of unknown, unsuspected and unanticipated Claims), if any, as well as those relating to any other Released Claims hereinabove mentioned or implied. Garcia

5 acknowledges and agrees that this waiver is an essential and material term of this Release and without such waiver Employer and the Company would not have agreed to make the payments described in Section 2, Section 3 and Section 4 above, and would not have agreed to the Bonus Upon Sale described in Section 7 above. Garcia further agrees that in the event he brings his own Claim in which he seeks damages against Employer or the Company, or in the event he seeks to recover against Employer or the Company in any Claim brought by a governmental agency on his behalf, this Release shall serve as a complete defense to such Claim to the maximum extent permitted by law.

11. Indemnification. Employer shall indemnify Garcia in accordance with and to the extent covered by Employer’s corporate charter, by-laws and Directors and Officers insurance policy.

(e) Choice of Law. All questions concerning the construction, validity and interpretation of this Agreement and the exhibits hereto will be governed by and construed in accordance with the internal laws of the State of Delaware, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware.

(f) Remedies. Each of the parties to this Agreement will be entitled to enforce its rights under this Agreement specifically, to recover damages and costs (including attorney’s fees) caused by any breach of any provision of this Agreement and to exercise all other rights existing in its favor. The parties hereto agree and acknowledge that money damages may not be an adequate remedy for any breach of the provisions of this Agreement and that any party may in its sole discretion apply to any court of law or equity of competent jurisdiction (without posting any bond or deposit) for specific performance and/or other injunctive relief in order to enforce or prevent any violations of the provisions of this Agreement.

(g) Amendment and Waiver. The provisions of this Agreement may be amended and waived only with the prior written consent of Employer, the Company and Garcia.
